3D printing is a powerful tool for creating practical solutions. In this video, I showcase five times where a simple, practical print recovered a problematic situation. If you need evidence that it’s useful to pick up some 3D design skills, this should be it.
If you need some thorough destructive testing, or some sweat/sunscreen licked off your arm, please get in contact with Bret and Jemaine.

Practical 3D printing is my favorite aspect of this whole hobby. One of my first prints was a clipped-in holder for the horizontal bars in my fridge. It took three prototypes before it snapped in, but the whole process was super-satisfying!
So sorry to hear about your dogs. That’s tough to take, losing two the same day to the same calamity.
So sorry to hear about your dogs.
A few practical 3D prints I've done:
-A cable holder for my electronics station--it holds four different USB cables ready to power stuff
-The door knob on the door to our garage was always sliding around in the hole in the door, so I designed and printed a spacer to keep it centered
-Too many monitor stand legs to mention
-A drawer that attaches on the side of my printer to hold wire brushes
-My wife likes to make ramen, and when she does, she opens the packets before they need to go in so they are ready, but she ends up making a mess when she puts them down, so I printed a little holder for her, with magnets glued into the bottom, that she can stick on the stove and slot her packets into and hold them upright.
As a home inspector, I measure the distance between two balusters in a handrail or guardrail along the side of stairs or a balcony. The standards for measuring this space is to test that a specific diameter sphere is not able to pass through the opening. Most inspectors simply use a tape measure to measure this space, but that's not necessarily accurate or convenient. I have never found any supplier who provides these specific diameter spheres (three different diameter measurements are needed under three different conditions) so I printed the curved shape of a hollow slice out of the center of a sphere that is the specific diameter that I need for testing the the space between two adjacent balusters. The wall thickness of my spherical shaped rings is only about 1 mm.
That's a great application! You might be on to something there.
Sorry for your loss of dogs. Great prints and builds! Also great use for chopped tape! ✌🏻
Few things make me happier than finally being able to print something practical.
Well done. Sometimes the hardest thing to do is to remember that a part can be made. More videos like this would be very helpful. Condolences on your dogs.
The first ever non-calibration-cube I printed was a replacement clip-in mount for my bike headlight. Ever since then I try to keep a 50-50 balance between fun and functional prints :)
I just want an entire channel of practical 3d prints lol
I could watch this stuff all day long
sorry to hear about your dogs man. I'm still struggling after loosing one of my 18 year old cats... with the other, now 19 also slowly losing the race.
Our previous dogs made it to old age, which was upsetting in it's own way watching them decline. This time they were only three years old, and then just gone. I hope your cat has a comfortable last part of its life.
I've used a ton of your videos to help me along with 3d printing over the years but this is one of my favorite videos you've done. I LOVE functional, practical, useful 3d printing and several of these are very clever! Thanks!
Practical prints are what really make the printers pay for themselves.
My favorite practical print was a small gear for an electric motor replacement ( a 3 dollar motor ) - the shaft was a different size than the original, I literally justified buying my printer for it, took me a bit to learn modeling, but a 10 minute print,, saved me a $1000 dollars ... 3 times now.
That's great.
my favorite practical print is the keyboard that i'm typing this on it's really nice to be able to just run off fully custom ergonomic things designed just for me
I love the chopped tape on your laptop.
one thing to add to the door lock thingy: make it captive by adding a keychain loop and tie some string or fishing line and attach it to the handle, like gas caps. I know they first time i would remove it, I would lose it
I recently had a 3d print save the day. My parents bought a new fridge and wanted to remodel the kitchen... but the table turned out to be ~8 too short for the new setup.
So I measured the dimensions of the legs, printed a set of raising blocks and it all fit nicely.
Nothing beats a good practical print! When my daughter moved from a full harness car seat to a booster, she strugled to buckle herself because the buckle would fall into the gap in the seat, so made essentially a doorstop shape with a slot in it to fit the short strap under the buckle, and it forced it to be held up so she could easily see and access the buckle when we get in the car. It works so well she still likes to have it and I had to make another when my son graduated seats too!
Recommendation for the first print: Make that part attached by a ring to the base of the handle. That way you can just swivel it off of the pin and it's unlikely to get lost.
i was thinking a little eyelet for a string, so that it'll hang from the door handle when not in use. yours would be a bit more work as it would require some careful measurement, but a much nicer solution once it's done
Last night I designed and printed out a display stand for a craft show to store some garden dibblers. Took less than an hour to design, prototype, and finalize the design.
One of my favorite practical prints was for a liquid ant bait station. Whenever it gets warm the gel inside seems to expand and bubble out. So I made an enclosure with peaks and valleys where the ants can travel but it also keeps the liquid inside, forming pools. I added screws to prevent my cats from eating the bait station gel as well.
Love the goats names. Flight of the concords rock!
Practical prints are always worth showing
Michael, please keep doing videos like this! Your design skills are awesome and you apply them so well!
All great ideas! Your channel is great, thanks for sharing w us!!
I once fixed a set of drawers so old that their plastic brackets were falling apart, even worse the company that made them was no longer around so buying more was out of the question.
Thankfully there was exactly one intact piece that I was able to replicate/print copies of, saving us the trouble of replacing everything entirely.
The "Mighty Car Mods" and "Flight of the Conchords" easter eggs in this video made me chuckle.
It is always great to see how other makers solve problems, thanks for the inspiration fuel!
That laptop cradle is brilliant.
Great. video, thanks Michael. Useful prints are the most satisfying to design and print. Sorry to hear about your dogs. Happy Christmas and New Year.
Great stuff!
Love the chopped stickers on the laptop!
Great video. Looks like quite a life ya got there! I do mostly this kind of design and print myself. It's awesome to need something and just make it!!
This is the best 3D printing channel on youtube, I HAVE SPOKEN!!!. I'm loving these practical prints, but it's the best anyway, hands down.
This was a very nice video, problem solving at its best
Thanks for the awesome video.
I made a TPU mat for a mixing bowl so it wouldn't slip.
I also made a stove utensils baskets with 6(2 for tongs on the side) compartments to keep everything separate and upright. Extruded a cool pattern into it and it looks and works better than anything I could buy.
Oh noes you will enrage the internet of 3d prints around food.
Great video mate
I had some dials on my washing machine that kept getting turned by mistake. We never use those functions, but I didn't want to take the knobs off, so I made a print that sits on the dials so they won't turn if you bump them. It has been working perfectly for several years now.
Simple and effective.
Awesome video mate - and so sorry to hear about the pups
I agree Michael. My 3D printer is a godsend. So many projects in the house and workshop and for friends too.
Practical printing! This is totally how I view owning a 3d printer. I've done a few downloaded models, but problem solving brackets and woodworking jigs is what I love most about 3d printing! Identity a problem that an object could solve, decide if its could be done with wood and avaliable tools. If not jump into onshape which you taught me and knock out a 3d print!
I'm kinda glad you didn't post the stl files for the completed projects.
Just had the bathroom door lock up as soon as I'd finished the video earlier.
Makes me want to figure out how to make one similar.
I live in an RV and I ALWAYS have a 3d Printer with me. I fix half of the headaches with it and always look for opportunities to solve other RVers issues as well.
The metal clip on our towel rack holder broke. I keep designing a new piece every few months and my skills in CAD and 3D printing improve. Great video and lots of fun watching the goats.
Over the last 10 years my printers have gradually moved from being a fun electronics hobby to being amazing tools.
At work we bought some rack mounted powerbars - with the worlds Easiest to press power switch that turns off power to critical network infrastructure if you look at it wrong.
I printed a little bracket that sandwiched between the rack mounting screws, and it provided a deep "bezel" around the switch. Day saved!! no accidental network outages! was a 20 minute print and my boss was super impressed.
Another one - We bought Logitech Tap tablets to control our conference rooms... but the wall mount was $155 and backordered for 12 weeks. I designed a flushmount, with better cable management, multiple mounting solutions... and for $2 in plastic vs $155. We have 20 of these tablets. That one job More than paid for the Prusa MK3S I had convinced my boss to buy for the IT department a year before.
I have a 1" (25mm) thick piece of dense foam I use for ripping sheet goods down. I was keeping it in my truck but needed to remove it whenever I wanted to use the truck. I then bought my 3d printer. After wrapping my head around FreeCad (I used to do drafting on paper), I came up with the idea for some simple brackets to mount the foam board overhead in my shed. They're in PLA now but I have plans to reprint them in PETG if the Texas heat gets to them.
Some time ago I needed some "feet" for some lawn chairs that were just bear open AL tubes and when you sat on them you would sink into the ground. Very easy to measure up what I needed and printed them out of PETG and no more sinking.
My favourite practical print was fixing one of the latches on an igloo branded coffee urn for work. The base of the latch had snapped when it fell of a cart cause of some newbies being dumb. I quickly replicated the design 1 for 1, and reassembled. It broke again in a tent incident a few weeks later so I beefed uf the design and printed it solid. Glad to say it's been going for years in same kind of rough and tumble environment.
Nice video. Yeah the practical prints are always the most satisfying IMHO. I like not going to the hardware store to get those drawer slide brackets and sliders. When they break, I just print a new one.
I can't count mine any more... The very first ones were something I did for my mom, tack-on hooks designed to work with those thermometer-shaped holes you are supposed to slide over a screw head. Haven't used any in years but the fun I had seeing the look on my mom's face when those came out of the "expensive doodad" she'd been so skeptical about was worth it.
The latest I designed myself (at least those I remember) were some parts for my car to replace some broken brackets in the center console. Other than that, battery size adapters, temperature sensor holders, battery wall holders, and similar knickknacks and doodads...
My humble Ender 3v2 from 3 years ago has paid for itself several times over with practical prints, bodging things back to funcional.
My favourite though is a milk bottle holder. Around here farmers have started selling their milk directly from machines - you bring your bottle and fill it up. Trouble is the bottle rolls around in the boot on the way home. A simple cylinder on a rectangle made in tinkercad (now upgraded to an extrude along path thing in fusion 360) keeps it upright and stops it spilling.
The next project is door handles too. The thread on the connecting screws that go through the door is wearing out on our old cheap door handles, and sometimes when you pull on the door the handle comes off in your hand. I will have to buy new door handles, but these days the rod that connects the door handles to the latch and works the latch when you twist the handle is a different size and won't fit through the old mortice locks. Without a 3D printer, I'd have to get the mortice locks changed on all the doors as well, but I should be able to keep the old rod and print up some shims so I can use the old mortice latches with the new door handles. A victory over the international door handle mafia!
Lastly, many thanks for your videos and your website (particularly printer calibration). They have been very helpful and have led me to try things I wouldn't otherwise have attempted
I enjoy practical 3d prints. My favorite but slightly glamorous print was making a replica of my cars vent and making it so it would hold my methonal controller.
I have seen similar mods but not for my exact vehicle.
good stuff Michael! for your door lock clips, i immediately thought that it would probably be pretty handy if you extended it to hang onto the handle. since they're round, it could be pivoted out of the way to lock the door but remain in place so it doesn't get lost, a bit like those hotel 'do not disturb' signs.
If I were to design the door lock clips then I'd place a tab opposite the opening in the ring. The tab would let someone hold onto the clip while putting it in place or removing it. The tab would stick out from the base of the door handle when the tab is pointing down but the clip may be rotated once in place so that the tab does not stick out.
One person below mentioned using a magnet to keep the clip with the door handle when not in use and a tab would be a great place to put the magnet. Or a hole could be designed into the middle of the tab so a string (or fishing line, or something like that) could be used to loop over the part of the handle that covers the part going through the door. An option could be to have a short line go through the hole in the tab to a magnet.
It might be a good idea to keep the key attached to the back of the handle in case the clip was taken out and then the person got locked out before replacing the clip. Place the key in a rounded half container with a magnet, or some other method to keep it attached, on each end of the long axis and place it on the back of the handle, near the base. Hopefully it would not add too much depth. This way the key would always be there when needed.
I love doing practical printing and have don a ton of them. I had a plastic screen guard for my back screen and one side broke. I simply took a pic, imported it into fusion and created a new one for the side that was missing.
Oh wow, the Ikea leg print is the reason I just took my printer out of the attic. This was the first video I randomly clicked on and you have the exact same problem as me with the same drawers. Thanks!
One or two practical but basic items. Some oblong inserts for the inside of the handles on a piece of rolling luggage which would no longer retract because the existing components had disintegrated. An odd little bracket to fix a tile to to allow access to a sliding door mechanism. Favourite is a cup holder insert for the back seat of a Porsche 911.
practical prints are my favorite, I print the occasionally benchy and storage solution but a majority of my printing is self-designed stuff I need to fix problems around the house. I've got a print that adjusts the angle of a projector in our bedroom which was initially held there with a bunch of coaster stacked awkwardly, and it hangs over the edge to keep it nicely square in case one of us swings our arm up in the middle of the night. I also designed up some marker holders with inserts on the back for magnets which holds ~10-15 dry erase for both my whiteboard and our fridge. I'm also currently working on a light blocker for something on my fish tank to help cut down on the light spill into some of the equipment which caused it to grow a ton of unnecessary algae, next step will be adding some clip-ons to the lights themselves to help cut down on the light spill into the rest of the room.
I printed an inlay for our kitchen drawer to organize everything nicely and effective in the available space.
I've made replacement drawer slide brackets for my kitchen. The originals in the built-in cabinets were nylon, and over the years they became brittle and started cracking. I designed new brackets to fit the existing slides, and made them symmetrical so I could use the same kind of bracket on both left and right sides.
Now I need to design a roof rack for my station wagon. (grin)
"Goat incident" indeed! Very nice and gives me renewed incentive to look at Onshape again.
Sorry to hear about your dogs, my condolences on your loss.
The main thing i learned: no goats - no problems! 😆
Awesome video! 👍😎
they bring unique problems, but they are so entertaining at the same time.
our kitchen extractor fan's knob broke. i printed a new one and it works great! prob my favourite practical 3d print!
LOL!! Bret and Jemaine!! Love Flight of the Conchords. :)
I made a hook that is a sideways h with a bent over top. The display self in the den is 1/2" glass but I wanted to hag my ball caps from the edge. I also wanted an easy way to remove them if I wanted to wear one. The hooks slide far enough onto the edge of the shelf to hold the weight of one hat hung on the small hook. With the hat in place, you can't really notice the hook's minimal size and none of them are permanently attached.
Most of what I print is for practical reasons. We bought a new kitchen sink faucet that has thefaucet head that you can unmount and pull out. The spring on top was too stiff and it arced the faucet head backwards a little when it was docked, so I created a version that attaches to the stock location but brings the faucet out at about a 30° angle. Works WAY better now. I also printed a phone mount for our baby stroller. I designed it to hold both mine and my wifes phones at the same time.
I made decorative end things for curtain rods, they are expensive to buy new when you need at least 8. Also the shower curtain kept falling down because its only force fit and I made holders for the ends.
Practical prints and more gratuitous goat footage? That's always a great combination!
I always enjoy getting the goats into a video where I can.
Thanks
A whole bunch of stuff, here's a non-exhaustive list:
Replacement headphone band.
Some parts to turn a pair of binoculars into a sun projector for the eclipse.
A tiny hose nipple to replace one that broke off a complicated injection molded part in a CPAP machine.
Spacers to adapt some replacement wheels to a lawnmower, to keep them centered where they were supposed to be.
A fixed-angle miter gauge for a table saw.
Something similar to a phone case, but for a blood sugar meter.
Extra-stubby screwdriver that takes standard bits(adds about 2mm to the length of the bit by itself).
Tweezers for holding very short finish nails(Couldn't start them without hitting my fingers).
I found low-powered screw guns for $10 at Harbor Freight Tools. I have been buying them for their motors which include a reduction gearset and a chuck that holds screwdriver bits. I 3D printed a new housing for the motor which has a flange that can be bolted to anything. I can press fit cheap screwdriver bits into other printed parts for a simple and easy attachment. I had a specific project I needed it for but have already made several more for other things.
The MCM tape on the laptop was an awesome crossover lol!
I was on one of their videos once, which was being sponsored by a game publisher. Therefore any rival logos had to be covered. I've never bothered to take the tape off since.
@@TeachingTech very cool!
Goats of the Conchords
I recently made a shelf for our ice cube bin in the freezer so the tray could sit underneath it, reclaiming a huge portion of space
Another one was a knife block insert (we had a bristle block style one, but those get really tight and near impossible to remove knives from)
A quick practical:
I was visiting my mother one day, and noticed that she had the power bar under her drafting table mounted with some packing tape. It looked awful, and appeared to have fallen apart a couple of times. Checking the bar, I saw that it had holes for mounting screws.
So, 10 minutes in TinkerCAD, and about two hours of printing later, I had a couple of hanging brackets that looked nice and wouldn't fall off randomly.
I was changing the locks after moving. One of the doors was drilled slightly too small, and didn't have enough clearance for the new latch to work. I had a hole saw in the correct size, but no way to keep it centered in the existing hole. I printed a spacer that fit on the hole saw arbor and kept it centered while re-drilling the door.
I prefer anything I print to actually have a use. I got tired of the little bumpers on those coiled spring door stops that screw into the baseboard dry-rotting and falling off for the cats to play with. Spent about 5 minutes in Fusion 360 to design a TPU replacement bumper and even less than that printing it. They work like a charm and kept me from having to buy new door stops.
My 3 most useful practical prints might be
- H-like brackets that hold led strip attached to L-shaped aluminium extrusion. One side is screwed to wall and another side was meant for a shade. Hefty enough to not droop over time
- Fan housing for 75mm sewer pipe for composting toilet ventilation
- Handles on top of resin printer lid and washer/curing lid. One hand operation
- Replacement nut handles for electric mover handle bar
My 4 most useful (yes it's Monty Python reference you weren't expecting 🤭 )
Oh, and replacement hinges for heated/cooled portable fridge case. Metal pins from original harder-than-optimal hinges and one of the very few prints in PETG (PLA would likely have worked as well).
I decided to replace my car's Double-Din factory radio with a Single-Din Pioneer. I could have easilly gotten a dash kit online, but they usually have a place for the radio and a cubby hole to fill in the space. Instead, i designed my own dash mount. The space under the radio was outfitted with features I wanted. A power button for manual amplifier override, amplifier gain knob, microphone for handsfree calling, ports for USB and Aux to the radio, two additional USB ports for charging stuff, and a captive 1/4-20 standoff nut for mounting an articulating arm for a phone holder.
Yeah - I am still amazed at how quickly I can gen up some widget to perform a specific task - from a template to install cabinet door knobs to a press to push a motorcycle handgrip onto the handlebar. I do most of my stuff in TinkerCad as it supports the complexity of things that I need - but am looking into learning true 3D CAD. I spent a lot of time with 2D AutoCAD in the past, so just need to move it to another dimension. So to speak...
tinkercad is great! i used it to make things way more complex than i should have before i started learning a professional cad program
My 3d printer has saved the day a few times. My wife bought a shelf and broke one of the dowels that came with it. Modeled a one and printed a replacement. Also printed a replacement knob for my buddy's kerosene heater, must have worked pretty good haven't heard any complaints for him on it.
I've been a subscriber for years, but haven't been getting any notifications in my stream. I came here to verify I had the right channel address to share on the Creality Redit community for some noobs who were doing things that would damage their printers over time, and you provide the information that will save them. I hope they watch your videos...
I have a save-the-day print I designed for my wife that clamps over the porch railing so she can hang Christmas lights without using wire-ties or zip-ties. They are printed with PET-G and do the job very nicely. I haven't posted them anywhere, but should. Another item was a funnel that fits in gallon water bottles for spill-free refilling. I use it every couple of days when I run my distiller to make distilled water for a CPAP machine and a clothes iron. I also made a small holder for some humidity/temp units that are small. I like to monitor the humidity in the house, so I know whether I'll need to dry my filament. Here in the Western deserts of the USA, the humidity rarely goes over 30% and is usually in the low 20s to upper teens. Currently, it's 29% where I'm sitting and it's been raining today.
Sorry to hear about the dogs ☹️
Useful 3D prints at our house include:
- Decorative rack that holds the wife's water bottle upside after rinsing and for storage
- Sugar dispenser that mounts through a hole in a jar, dispenses a measured amount due to multiple chambers.
- Nozzle for watering potted plants at a low rate, attached to 1.25L bottles
- whiteboard marker holders with mangets inside
- Phone charger mount with wireless charger inside
- Bag hook that skewers through the head rest post on the car, has print in place chain
The list in my house goes on.
I make 3D printed car parts also, including:
- Blowoff valve cover with whistles attached.
- Prototype brake conversion brackets for trial fitment of weird and wonderful brake conversions
- Prototype gear shifter mechanism at gearbox
- Currently trying to make end use 3D printed gear shifter out of ABS
Condolences on the loss of your dogs. I'll look forward to prints for dogs If/when you adopt another.
I worked at a pool company that routinely installed auto fill mechanisms too high. The float valve was never able to close because it couldn't reach the water. In classic, incompetent and lazy style, my supervisors decided to just disconnect the auto fill from the spigot to "solve" the problem. I took it upon myself to print a longer connection rod for the float so that it would submerge and close the valve. It worked like a charm, but my supervisors were not happy that I'd made them look like idiots (because they totally needed my help for that) and eventually fired me for continually fixing their mistakes. Probably for the best, as they're now in the final stages of bankruptcy and being sued by several of their customers.
3D printing really allows you to be crazy imaginative with fixing things. We recently fixed a partially broken clothes airer that someone left on the side of the road and saved ourselves a nice bit of cash.
Sorry to hear about your dogs by the way :( Good job getting on top of it fast to help save your other furry friends!
Nice MCM sticker set
To me this what 3D printing is for. I made some sextagonal porch posts and needed some caps for them so I designed and printed some ball top caps. My 3D printer has payed for itself in just a couple of projects.
A cowboy plumber made a complete hash of our bathroom renovation more than 15 years ago. We brought in someone to fix it when it became unbearable, but he was unwilling to pull down the enormous, thick tiles due to the damage it would cause. Instead he mounted some flush panels over the tiles. All this time, there was no lock on the bathroom door. There was space on the door itself for a normal lock, but nowhere in the frame or wall to mount the receiver. A quick design in Tinkercad and I had a receiver that mounts as part of the door latch and has the receiver in the correct place. I printed it way too resilient though - it needed to be sacrificial. If there was a problem inside and we kicked the door to get inside, the hinges would go before my print.
great video! now to get my wife to sit still and watch it so that she begins to understand 😂
Wow I didn't realize you had a little farm going on in the backyard. Sorry to hear about your dogs, I live in South Florida and our wildlife can be quite dangerous to our pets. From toxic frogs to alligators it seems like something is always out to get us. Great job on using 3D prints to fix things around the house
That clip for the door lock needs a loop so you can run a string through it and hang it on the knob when not in use. Or print a hook onto it that goes around the knob, like a number 3. Just so nobody loses them for you.
Rocking the Williams on the day Logibear is back for 2024. Nice.
I feel he probably deserved another year to learn, but I'm also a bi disappointed that someone like Liam Lawson didn't get the seat.
5:30 this exact thing was the case for both the wardrobes for my wire basket rack too.. it's almost like it was intentionally made just a bit too big :I
the key take away here is that those goats are absolute menaces to society!
Cool video! A question that arose to me was since you have so many machines, how do you take care of air pollution? Already saw some videos on it, but your take on it would be interesting on it too!
Very sorry to hear about your dogs. That was always one of my biggest fears when i had my last dog knowing we had copperheads and water moccasins in our yard.
Thinking of all the ways to prevent goats from destructing things is a full time job :) Tip - if your goats aren't milking/breeding/working they really don't need grain. Hay is sufficient and ideal for their rumens. You can eliminate the grain completely and not attract rodents anymore. Your goats won't be happy about it I'm sure, but you can wean them slowly over time. :)
If either of your goats are wethers (castrated males), it's preferable that they're not on grain as that can contribute to urinary calculi issues which can lead to very painful deaths (their urinary track gets blocked, their bladders swell up and burst). Wethers are susceptible to urinary calculi issues because the castration stunts the development of their urinary tracts.
If your goats are girls, it's less of a concern, but I'd still vote for eliminating the grain at least for the sake of the rodent issue!
Sorry to be "that person" in the comments, but as a fellow goat lover, I just wanted to share this info in case it's helpful to you or someone else reading.
This was a great video and I love your solutions! Our goat barn features a 3d printed remote light holder as well as a power strip holder.
I;m always very wary of using 3d printed parts in anything other than guaranteed very low load or strictly in compression after a friend 3d printed a bunch of shower curtain hooks which were fine holding up a shower curtain, but absolutely couldn't take the weight of a person slipping in the shower and trying to steady themselves...
(however there is a bit of my motorbike's fairing that's held on by a 3d-printed bracket repair hack job so i'm hardly a paragon of good ideas myself)
Make a remote controlled bb turret to deter the rats!😂
