I'm building a giant excavator using the 3D printed Miranda Blocks that I designed to build the Go Kart to race Matt Denton and his lego inspired Go Kart. When I started building the Go Kart I realised that there were a lot of improvements that could be done to the blocks but Iterating the design on that monstrous scale was going to take a lot of time and be quite wasteful so I created this scaled down version of the blocks which took a loooot of filament so go and send some love to PolyMaker for letting me go wild with their filament! (aff link): bit.ly/3i4PEkd
As the goal of the blocks is to be able to use and reuse them to prototype different projects I needed a project with a little bit more punch than a car so I decided to try and build an excavator.
This excavator design is already too big for these blocks but that's intentional as I want to test the limits of the design so I can be sure that I thought of every detail before starting to print these at full scale.

I really like the idea of these blocks. I can only imagine how much print time is saved with every one of these blocks you can re-use in another project. :)
It also dawned on me, if you had one of those conveyor belt 3D printers, you could make arbitrarily long beams that are compatible with Miranda blocks. :)
I've been thinking about getting one just for that
@@ivanmirandawastaken you'll buy one and not make one??
@@ivanmirandawastaken or building a giant one? 😜
@@ivanmirandawastaken cool, and if you make your own, you could build the conveyor from Miranda blocks. hehehe :)
Flip the nuts for bearing mount- genius 🤯
Normal 3d print channels: look at the huge prints!! They are massive
Ivan: this is the scaled down version I'm sorry
Much love, awesome project as always
9:56 flashback from 'Why Mechanics Hate Engineers' ;)
Yep, that was totally missed in cad
I like the screwdriver. I think Meccano would be a better product if you could attach the fasteners more quickly.
Each time I see you use these blocks I am amazed by all different uses. You make if look so simple but as an engineer I recognize the amount of work that has been put into the design of this system.
I am envious of the amount of filament you use.
I virtually create my versions and sit on them for some time before printing before getting the courage to make the 'final version'. All this to save filament haha
8:12 - I'd just like to point out that the bearings you used seem to be purely radial. The base rotation creates axial and radial force, but the axial part is much more significant. Those bearings might break.
True ! A couple of bearings beetween the horizontal parts would make it stiffer and more durable👍
He might be happier adding a thrust bearing or just using a 'lazy susan' bearing. (I mean, there are bearings specifically for this, but they're specialized enough to be expensive...)
Im pretty sure the bearings despite not being designed for that use case are not the weak links in the chain here.
Glad I'm not the only one who thought this.
Radial bearings have more than enough load bearing capacity in axial direction than is needed here. This won't break anytime soon.
So we can eventually get steel miranda blocks as well. That is an interesting prospect.
That would cost an arm and a leg but worth it
"I was working on this big project, so in order to make sure it would work, I decided to start another big project" ~Ivan, basically.
Not that I'm complaining, this is awesome, and these blocks are amazing. I kinda want to print out some even smaller ones for my kids and me to play with..
Ivan Miranda, the only man in the world to successfully dial in a 3D printer 😬
This reminds me of the old Lego Duplo Toolo series .. Such a cool idea!
Ivan I wish you could post the amount test and failed prints !
This is awesome. One note. The arm on an excavator isn't offset; the cab is.
Now I've got another project to add to my list. This will be good fun
OH wow, Ivan, you rock with these amazing designed blocks! @polymaker3d Thank you for helping to sponsor this channel!
The 3d printed screwdriver had me laughing a bit there. Great build
Will definitely get used as a hammer at some point..
@@inventiveowl395 Or as a chisel, just in case the refrigator gets too cold.
Amazing Ivan! Love how you made it fully parametric with values! I need to do that more often in my designs!
A set of these in CF Nylon would be a super useful jig system for so many projects. Kinda pricey to pint in the large sizes.
I need to get at it and make some gridfinity too.
If you need something that strong, why not use alu extrusions? They're like Legos for engineers!
Polymaker was probably like "We should just agree to provide all the filament he needs. I mean, how much could one person possibly use?"
They probably had to open another factory just for you :P
😅
Love the 3D printed screwdriver. Very RepRap spirit :)
AMAZING REALLY CRAZY JOB.
I ALSO TRIED PRINTING BLOCKS LIKE LEGO, BUT THESE ARE REALLY HUGE BRAVO!
you live as close to my dream life as humanly possible.. ever since i was a kid i was taking apart all my toys and rebuilding other things out of them. anything with a motor was ripped apart and cars and very simple robots were built. now as an adult i work maintinenece in a machine shop where i get to play with fun stuff all day and be paid for it but my dream is to rent a warehouse and basically do exactly what you do.. Play all day with awesome stuff i built. and since 3d printing becoming a thing and cnc mills/routers became desktop sized and able to be bought for only a few hundred bucks, it opened up the possibilities from parts i melted together with a lighter to make stuff kinda work to making exactly the parts i need, when i need them, and making all the ideas in my brain a physical tangible reality. we live in an awesome time. Keep doing exactly what youre doing and ill continue subbing and living vicariously through your videos!!! haha
This is GREAT... Loved this, and my mind start to spin with all the possible projects that could be done this way in larger scale, simplifying real world prototype builds using standardized modules.. you are taking everything to another level Ivan, and I LOVE it !
Another big block builder 👍 nice one Ivan. I got started on the big block but Matt also. I have the large bulldozer Matt did and im working on the technic go kart kit 42048 and the race truck, both five times Lego scale to match the bulldozer 😁
btw id reccomend checking out brass bushings for joints. For anything that doesn't require fast movement for more than 360 degrees, bushings will be stronger and cheaper. Bushings for low speed and high torque, bearings for high speed and low torque.
Awesome project, you should try to get threaded rod with a 2 or 3 start thread, then the movement would be much faster. They use this on certain valves that need to be opened or closed rapidly
Having a 3D printer in order to be able to print custom parts.
Ivan: I printed a universal system to build things from. :D
.
Awesome video man! Love what you do with technology.
For the pegs I'll bet you could embed a steel shaft/threaded rod(s) into it for pieces that need extra rigidity, nuts at the ends to hold it all in compression.
Red filament gonna stonk when ivan start print
I love you vids so amazingl
No "SPACERS"???
wonder how well plywood would work for those flat beams
I guess it would do well, It is just a matter of getting the same dimensions and features on the plywood
Reminds me of the Erector sets from the 1950's when I was a kid.
I am always impressed! 👍👍👏👏
Super size techno
Those poor little servos! It might be good to put an ammeter on the power supply to show how hard they are working.
Very! At least the one at the bottom of the arm. Everything in this project should be 50% smaller
You, your projects and Polymaker are awesome!! 😀
Wow this is genius, it's like a giant erector set with home printed pieces, the possibilities are endless!!
got a challenge for ya, multi material large format belt 3D printer... with that you could make almost anything in one print.
Great work Ivan
As always
Though excavators don’t have the arm on the side when in bigger sizes .
Nor on the smaller ones either. It just appears that way.
soon we'll see a video of Ivan building a 3D printer made up of Miranda blocks to print bigger/longer Miranda blocks
Suggestion: Change the last part with a lamp and add a remote control maybe with some Alexa routine.
Unbelievable!!!
Something "Simple" XD. Ivan is the GOAT :D
Hey Ivan, love the looks of this! One note that might be helpful-- typically in these sorts of rotating turntable arrangements, the small gear (attached to the servo) is stationary, while the big gear moves. Based on 11:52 it seems you currently have it set up in the opposite way. If you run into issues with the servo, consider switching it around! :)
What's nice about doing it this way is that all the wires and the controller/battery/radio get to live on the platform, without the need for slip rings or anything.
Beautiful work as always. How hard would it be to use stepper motors in your linear actuators? I think that might solve the speed problem. Keep up the good work love your stuff.
interesting DIY hammer to put together the pieces.
I think it's be so cool if you started using hydraulics in some of these. Small diameter hard pipe is pretty easy to work with and conceptually it's all pretty simple too. I think the hardest thing might actually be to find a hydraulic pump that is small and quiet enough for indoor use haha.
I'd just like to point out that no the boom on the excavator isn't offset from the line of rotation.
Very interesting project, as always. The only point I'd consider is the matter that excavators do not use actuators but pneumatic pumps because they take far less room than the actuators. And because the load can be much higher. I think there's a way to make a pump with bricks.
Excavators actually use hydraulic pistons and pumps but I need to compromise sometimes.
@@ivanmirandawastaken i guessed that was the reason. In Lego Technic there are the pumps too 😉. Anyway as always great project. Wish I could have room for such projects
Tracks to make it mobile next? Then a dump truck to fill with it? 🙂
Didn't go with some small RC drive motors? Hacked servos, instead? Interesting.
However, can't argue with the results. This is very impressive.
Super projet, mais pourrait-on mettre dès servomoteur plus puissant ?!
You can just pull the pin out of the end gear :)
Awesome video as always Ivan :) I'm looking forward to see the next video :)
So when will you go water-hydraulic?😁
¨You just reinvented the old wodden meccano or what it name was, that I remember from my childhood, more than 30 years ago.. :D
You are great !
Doesn't that particular servo model come in a 360 degree variant though? At least that's what I see on aliexpress
Maybe, but not the ones I had.
You should attach it to the tank
You know your stuff. 👍
Love It
wonderful design! you sell that as a kit!
At this point the first thing that will break are the threads of the screws.
Finally someone made lego for men 😮
I think you need to 3D print your storage bins.
The video just started but I am already sure I will like your screwdriver tool most! :D
Ok, your smile when it started turning just beat it :D
Shares in red filament just went up.
Hey Ivan have you tried using the trick of saturating parts with crazy glue to increase their strength??
continuous rotation servos are just as easy to buy as regular servos.
also, i think that M logo on the bucket teeth may be copyrighted by BMW.
oh to live in a world where companies can't sue you over a singular letter
Great! Try to use a tube with thread at and, it looks like a hydraulic cylinder and the threaded rod is shorter 😁👌
(you clearly don't need it, but) Have you ever considered a ratcheting version of the miranda-screw-driver?
Amazing project! Just by curiosity, what is the cost of the aluminium 3D printed part? :) Thank you and keep going! :D
Looks great but I think you have a very weak point at where the arm attaches to the base with only 4 bolts there and nothing else holding it together, unlike the triangle structure pieces of the arm.
Build 3d printer with these blocks!!!
ivan if you remember the big 3d printer you made it could you give me a link to thys hiudge bed heater 500x500?
Cool
12:10 O_____O That is a LOT of filament... Mind sending some my way please?
I wish you lived near me … I need someone like you to custom print me a travel box for my big manual Battipav tile cutter …. I have to use the cardboard box it can in and it drives me insane I can’t get a case / box for it cos it’s 1300mm long 🤦🏻 loving the channel btw 😀🙌🏼
I've watched your engineering and design skills evolve over many printers and it never ceases to confirm the concept that both Musk and Edison champion. The genius idiot's way of it is to fail your way to success by learning from each failure how to actually design and engineer wild imaginings into reality. Thanks for another confirmation of this.
musk failed his way to success by coming to America with so many emeralds in his pockets that he had to pawn them off because they were falling onto the streets
@@theninjascientist689 It is interesting to look at the evolution, psyche, and what drives those that have risen to the top of the heap and create viable, long-lived enterprises. In a majority of their cases, financial success is simply the managed result of their need to take controlled risks to accomplish their dreams.
its the more fun way to learn for sure, but if you get good enough with CAD you can improve your design through simulation, to avoid having to do too much building and failing.
Are the stls for these blocks available anywhere? I’d love to print some out!
What is the little thing you're plugging the motors into to test them?
nuts, and bolts
screw (actuator) is always nice
You lobotomized that poor servo! 🤪
Вот это размер ) круто!
Still puzzled how this big parts are printed warping free?
imagine putting a camera on it, so you can use it with a vr
Any reason why the modified servo and not a stepper?
why you take dc servo motors and not more manageable stepper motors
Dang impressive as always. 👍
Hi Ivan, you are simply a genius at the work you do. I think renaming your channel to "incredible Scientist" would be more appropriate 😁
will the files for the blocks be released in the future? maybe for sale or something?
Is it possible for you to upload the fussion 360 or stl files so all of us can dowload it, i did not find it on your website so them are maybe for private use.
Collab with James Bruton!
you should 3d print in some different colors
Did he show the price of the metal part?
Need bigger/stronger servos
Why do people modify servo motors instead of using regular motors? This never made sense to me. Is it a problem with the driver circuit?
I’ve never understood why people convert servos to continuous rotation, you lose the main features of the servo. Why not just use a normal DC motor with a gearbox? Is it because the servo has a built in driver and only needs one connection to control the motor?
