Would it be possible to modify the tension mechanism to remove the allen key and use some quick-lock mechanism with a small lever? Maybe similar to the quick levers for bike wheels? It would be great if the rubber band pre-tension could be removed or reapplied in just some seconds with no need of a tool, for easy daily use.
@@perwestermark8920 This would be difficult as the printed plastic is not that strong. I used a simple, compact and rather reliable solution, but requiring the use of an allen key.
You need to make something like this that shoots steel bb's next !!!! It could shoot steel 6mm bbs.. To make it legal all you would have to do is use the correct amount of rubber to make it under whatever joule limit is in your country ;] All your designs are really cool man..
Jorge, you are a brilliant person sir. “Stupid” is never a word I would use to describe ANY aspect of you. 3D printing is simply a skill you have yet to collect.
It doesn't have to be just the pinky, too, the whole hand grip could, theoretically, move with the lever action, then be gripped in place with the hand... I don't know the laws around this type of stuff, so I don't know if that would change the legality of the device
I think it was a humble way to say "I don't have the time to handle this manufacturing method". Because it takes quiet some time to design and print stuff like this. As a guy who makes a living out of FDM printing, I have a lot of respect for Lucasz because what he shows here is a masterpiece.
After week of printing and assembling it is finally alive, and well... its one of the top 3 items that ive printed after 8yrs in 3d printing! Major kudos @Łukasz!!!
I think there would be an optional further improvement by having a quick-release to tension/untension the rubber band so no allen key is needed. With a quick-release, it could be tensioned in 5 seconds making it so much quicker if someone wants to shoot every day.
In extremis you could just hook the block over the lug, I think. You'd risk it jumping off, and shaking the nut free, but that could be glued in...Sometimes a pause to think is useful.
@@ernststravoblofeld You'd have to put the tension release at the other end of the band, then, because that's the only part which is dynamic in the action. However, that's a really bad idea, because the way it's been designed transfers the tension to what sounds like a really solid catch at the front, whereas anything in that area to the rear may not be. Here, KISS certainly applies: don't forget you're dealing with a weapon.
Even just a spring and washer under the bolt seems like it might work, but yeah professionally it should use a detent retaining pin. Flip out in half a second auto-locking, and fold up with a pin press.
I basically got into printing because of this. Bought a second larger printer to run the large single piece version of parts and am very excited to see how it turns out. The creator's file set and guide is amazing and beyond worth paying him for!
I didn't get into 3d printing FOR this, but it is definitely the type of awesome, functional kind of printing I hoped I could do. And, additionally, almost convinces me I should invest in a larger bed printer as well!
would there be any way to modify the files so its has a lever action style loop for spincocking, makes one handed use easier and removes the need for the latch on the grip making since it would be easier to hold closed.
Beautiful, sleek and compact design. Imagine if your designs were all optimized and 3d printed? Or at least those that you are planning to bring to market. Well, the plans would also be enough
Did I just hear that right, someone from Poland is teaching someone from Germany how to modify a weapon, this is a great new world, you are the man Joerg, thanks for always trying to just be about the fun side of things.
I learnt a trick from a friend of the family on how to make rubber bands last a very long time. Put them in the fridge (not the freezer, just the fridge). I have had rubber bands for over 10 years in the fridge and they last forever. Also CA (superglue) lasts many years in the fridge as well, just put the CA glue in multiple plastic bags just in case so no fumes go in the fridge.
Hi, I buyed the stl files for about 7 euros and printed whole adderini project a few days ago. The pieces still need sand work to adjust properly, find the springs..... and I'm thinking about changing rubber bands for an 80 pounds pistol bow with string, so probably metal trigger will be needed or at minimum change the original one system as it only relies on a spring to hold string. I plan also to add an airsoft stock and a safe. It is a huge project so there is a lot of work for me to do, but first I will bring this thing to work as it is and then try my mods. For those who want to print one, it took me 4 days to print with an Anycubic Mega X and 1Kg of black PLA (1/2 Kg of each if you use two colours). Printed just following printing instructions in the pdf. I suggest to print it in PETG as PLA is worst for deal with tension and heat. To make it a rifle instead a pistol you only need to edit propper stl files in Fusion 360, AutoCad or any other and make adjustments, but take in consideration that you will need metal parts attached to build it so it won't brake. Eddited due to my poor english.....
YOU are "da man" Joerg! I watch your videos not only to inspire me, but also to pick some of your joy and make my days better just seeing your happiness for doing what you love and that smile in your face.
But Joerg, 3D printing is not hard at all. It just feels like a barrier, but you can always summon someone who is in 3D printing and he going to kickstart you in under a day - including basics of using CAD, setting up the printer itself and uploading your task into it. And the next update to a gun laws in Germany will ban 3D printers :)
As with an RPG launcher, one must incorporate a specific number of spins, reaching 920 meters prior to arming. To much risk involved in shock, centerfire primer tip detonation for this idea to work.
For safety you probably want something like a ripcord safety where a fishing line is tied to it so it must exceed that distance. If you just want a toy print a cupped tip and put in those "snap its" which are the little bags of rocks that detonate when you throw them on the ground or compress them and available almost anywhere in the US near July 4th. That way you get a cool little flash at night but without damaging anything.
you know, joerg, the most impressive thing about this channel is not the content itself, but more of how this channel always manages to impress me. just when i thought ive seen it all, there will always be another video which is genuinely interesting to see. really, this has gone on over about a hundred times now. truly impressive!
Would love to see this employed as a home defense scenario (broadhead through ballistic gelatin, leather, and cotton fabric)! Much more maneuverable in close quarters.
You have the hands and brain of an engineer Joerg, and you could easily learn to use a 3D printer! Don't put yourself down and say you are "too stupid" because you are one the most ingenious people on this platform... otherwise, why would people want to collaborate with you and make your ideas into very successful products that thousands of people all over the world continue to use and enjoy?! You can make anything you imagine with your two hands and that is most definatley NOT stupid! I Myself, and many others im sure, consider you a genius and also a lovely, big hearted and funny bloke. With the best catchphrase on UA-cam! "LET ME SHOW YOU ITS FEATURES!" absolute GOLD Joerg
God dam it.. I’ve just ordered the Steambow Stinger 2 Compact Pistol but now this next design is out, it’s only a matter of time before Steambow bring out their own version & I’ll have to buy that as well lol
make it with a lever action style loop for spincocking, makes one handed use easier and removes the need for the latch on the grip making it easier to hold closed
The internet is for porn? Nope, it´s for bringing crative Minds together who can build awesome Things together without any great effort! Awesome work joerg and Lukasz !
Wait till you find out there aee youtubechannels that did DIY biohacking to GMO on of the creators to produce lactase enzyme (thus remove his lactose intolerance)
This definitely needs to go commercial. So neat! What would also be cool is the addition of a a wire collapsible stock for better stability. This would allow for the overall compactness to be maintained and shot like a pistol, but quickly deployed for more precise shooting. Those are usually terrible on firearms because they are uncomfortable with recoil but would be perfect for this.
I've also made an adderini. Thank you for sharing the file. However, since it is a plastic made of a 3D printer, it has a disadvantage that it breaks easily. The front part is often broken.
The major design flaw for Adderini is the moving rail where scope or red dot is mounted at, this section of pistol-bow should be designed to be stationary and either be a attachable piece that connects to lower or actually printed as one piece with lower receiver. A stationary mount is better to keep aim for user and having to refocus on a moving red dot or scope gets disorientating and slows down one's retargeting.
Imagine trying to find your way out a dense, dark woods...... and hearing that laugh! I don't know about satisfied, but I'll think about it after I change into my brown pants! FR
Idea use the same type of spring used in a tape measure attach it to a sled that hooks onto the bow string so every time it fires the spring gets put under tension and like a tape measure draws itself back in and ready to fire again.
Nice! I would have put a small alan key on each rubber band section at the top with a small flat top so that all you had to do is turn it to tighten or losen in order to save the rubber band during storage! That would have been even better but omg that's amazing!
Considering how frequently you need an alan key to make changes to this, I'd have probably put a little place on the weapon that the alan key could push fit into. That way, you always have the tool you need (to swap things on and off the rail, and relieve the tension of the bands) if you have the crossbow in hand. :)
@@StevenIngram True I was thinking of a ring of metal at the top of these holes where the key fits in being secured with a smaller ring attached to the keys on each side preventing them from being pulled out, or simply bypassing the need for an alan wrench and just making the key one bit screw with a stopper at the bottom of the screw allowing it enough spin to release the rubber arms but not enough for them to pop out of the device entirely.
Even just a spring and washer under the bolt seems like it might work, but professionally designed it should use a detent retaining pin. Flip out in half a second auto-locking, and fold up with a pin press.
Great design, but there are some slight issues if you do make it. If you use crossbow limbs, they pack a ton of force. The cocking lever needs to be reinforced or there will be bending issues. The mag catch spring, lever latch spring, and the trigger spring needs to be stronger than the instructions. Otherwise, absolutely blows away the original pistol crossbow in ease of use and effortless to cock.
Few improvements: - obligatory "printed objects should be designed to have as few fasteeners as possible" - since its not held drawn by force, might as well make it multi shot. - you can add more power by also using the forward movmement of the tension arm as a power stroke (either via a 2nd half as powerful rubber band, or via mechanism) -the biggest influenc eon penetration is projectile speed... ...hence steps need to be taken to increase it. First should be employing a shorter but stronger rubber band. And using string + pulley to transfer the energy. (As energy that goes into acceleratin the rubber band is wasted. Thus the smaller band you can get away with the better. Also if you can pick between short and long, pcik short, as that means less speed on the partof the band close to the projectile - and momentum is proportionsl to speed squared)
I have been printing similar crossbows and compound bows using the plastic as the limbs and just shooting bbq skewers. Not nearly the same power. I will have to to try this out, rubber is defiantly the way to go for force.
You have great ideas and a gift for creating cool and totally new products, great innovation Jorge 🤙👌👍 When you love what you do then it shows with the unique inventions you keep making for your customers.. Love the channel ❤️ Ur optimisation and good energy projected with n your unique and hilarious presentation style.. 🙏👌🇬🇧
I actually had a lot of Europeans in the G+ 3D Printing community have a shit-fit because I allowed things like this in the community. I wish more people could see the awesome engineering and ingenuity required to make something like this.
i made some of these sling bows using no metal parts at all even the blots i 3D printed & thay work super good considering all i used was plastic hockey tape & rubber .. i call it the canadian unMetal detector special modd 007
That's what I want, I've got a design in mind that can be made from sheet metal but its going to need some more design work. I'm not sure what people would be willing to pay for one (it won't be a super cheap $100, but I think $300 would be possible), and scalable from 1 motor up to 4, however I'm not seeing high power brushless motors like I wanted to use because I want some insane fire rate with lots of power. What I'm looking at would probably be semi-auto with up to 2 shots per second depending on draw weight. This example so far has raised over $1500, and its barely been out, so considering that I could probably do similar in a week that's really not bad. If you think a lot of people would want to buy a full auto electric and could sell at least 1000 units (otherwise the cost is going to be pretty high for reasonable profit) then I could spend some time and resources making one.
For you Non-Germans who wonder why it wouldn’t be a weapon in our law if the lever lock weren’t there: Without lever lock there is no energy saved and stored by itself, just like with an arrow which you need to hold to preserve the energy, thus the ingenious idea with the pinky assistent which holds the lever in place.
So, trollish good looks and strength, reflexes like a 300 kph cat - driving his wife's Porsche on the Autobahn, gifted inventor, world traveller, a laugh that should frighten creatures from bad places and stupid. Hmmmm. I'll buy the first six, but the last doesn't seen to fit at all. More like you like to "do it the old fashioned way"- with your hands, I'm thinking. BTW, another great, true addition to the Slingshot Channel! FR
Joerg, the other day a thought came to my mind of a device to help loading crossbow. Imagine a standing "rack" in wich you can push your crosbow with your bodyweight and the sides of it "squishes" the crosbow arms, hence helping in the cocking process.
I would love to see post-apo tv show or webseries, where one of the characters or several characters would use Joergs weapons to fight enemies. Some of them may even have 3D printed versions, some of them just made from scrapwood. It makes more sense than normal weapons because ordinary "heroes" usually don't have access to those (unless you live in the USA I guess)
In terms of target shooting, this very good. However, there is one thing that could be potentially improved. That would be where the sights are located. Having a sight on a moving part could be a bit of a problem when trying to adjust it, because there could be a chance it does not sit in exactly the same position. This is why target pistol sights are not located on the reciprocating slide (or bolt, or whatever; reciprocating mass is what it is) and is instead located on top of a piece that sits just above it. This prevents that from being a problem. However, given this is not semi-automatic, and that basically the whole bow is what reciprocates, I suppose that isn't much of an issue at all. This really is a good design.
You are mistaken. The "moving part" also contains the arrow groove, which is the "barrel" of the weapon. Therefore it makes total sense to attach the aiming device to that part.
Hope you like this new "toy". Thanks Joerg for new inventions and great videos :) Best regards.
is awesome
Would it be possible to modify the tension mechanism to remove the allen key and use some quick-lock mechanism with a small lever? Maybe similar to the quick levers for bike wheels?

and its very easy..especially for someone with a mechanical mind like Joerg
A true backyard genius.
I think it meant joke. And it also greatly shows his humility.
The printing part yes...the 3d design of the parts in a CAD...not that easy... but still can be done
whats with the ass kissing?
Joerg now has a safety T-shirt with Joerg on it.
He is now bulletproof.
Ha! Bullets lack the courage to fly in his direction.
the design alone is already awsome. looks so futuristic
The beginning of an even better masterpiece
It is so obvious, that this idea should result in an steambow product, with that pinky addition. A product crossover Sprave, Janikowski + Steambow.
It doesn't have to be just the pinky, too, the whole hand grip could, theoretically, move with the lever action, then be gripped in place with the hand... I don't know the laws around this type of stuff, so I don't know if that would change the legality of the device
6:02 « I’m too stoopid to use 3D printers »
Also Joerg : *Proceeds to create a war weapon with a branch and a fork*
When you can no longer MacGyver a solution, you'll have to Sprave it. At least a fellow can hope.
Dont forg3t the artillery cannon with cardboard and rubberband.
I await the dat that the anti-proliferation treaty expires and Jeorg gets to collaborate with Colin Furze.
I think it was a humble way to say "I don't have the time to handle this manufacturing method". Because it takes quiet some time to design and print stuff like this. As a guy who makes a living out of FDM printing, I have a lot of respect for Lucasz because what he shows here is a masterpiece.

NEXT video please: rapid fire the whole magazine at 5 meters and show us the target as it impacts. Thanks!
Best pistol bow I've ever seen. Thanks for sharing Joerg!
I think there would be an optional further improvement by having a quick-release to tension/untension the rubber band so no allen key is needed. With a quick-release, it could be tensioned in 5 seconds making it so much quicker if someone wants to shoot every day.
In extremis you could just hook the block over the lug, I think. You'd risk it jumping off, and shaking the nut free, but that could be glued in...Sometimes a pause to think is useful.
You could replace the allen-key screw with a wing-head screw, then no tools would be needed.
I was thinking about a catch that would tension the bands the first time you cock it.
@@ernststravoblofeld You'd have to put the tension release at the other end of the band, then, because that's the only part which is dynamic in the action. However, that's a really bad idea, because the way it's been designed transfers the tension to what sounds like a really solid catch at the front, whereas anything in that area to the rear may not be.

(As energy that goes into acceleratin the rubber band is wasted. Thus the smaller band you can get away with the better. Also if you can pick between short and long, pcik short, as that means less speed on the partof the band close to the projectile - and momentum is proportionsl to speed squared)

I love this! Finally a reason to buy a 3D printer!
I have been printing similar crossbows and compound bows using the plastic as the limbs and just shooting bbq skewers. Not nearly the same power. I will have to to try this out, rubber is defiantly the way to go for force.
Brilliant!
Why not put those small bow arms under tenssion using a flat torsion spring as well so that they rotate forward adding more power.
An ABSOLUTE AWESOME Pistol Crossbow right there, no fraking doubt about that 😎👍
I've always been happy to just admire the inventions on this channel from a safe distance. but damn me, I want this.
the quality of the print is crazy
Looks like something from the Mass Effect games.
That thing really looked gorgeous.
I instant order this...awesome measurements!!! Will you take orders? Stay awesome!
That's awesome, and I would pay good money for a rifle version with 60-70 pound draw, and about 4 times the draw length.
You have great ideas and a gift for creating cool and totally new products, great innovation Jorge 🤙👌👍
When you love what you do then it shows with the unique inventions you keep making for your customers..
Love the channel ❤️ Ur optimisation and good energy projected with n your unique and hilarious presentation style.. 🙏👌🇬🇧
I actually had a lot of Europeans in the G+ 3D Printing community have a shit-fit because I allowed things like this in the community. I wish more people could see the awesome engineering and ingenuity required to make something like this.
That is a slick looking crossbow pistol you got there
I'd be interested a little bigger version with folding stock and a considerably longer powerstroke.
i made some of these sling bows using no metal parts at all even the blots i 3D printed & thay work super good considering all i used was plastic hockey tape & rubber .. i call it the canadian unMetal detector special modd 007
Loved it Mr. J! Respect and Godspeed my brother.
Was wondering if you could make the same crossbow pistol from far cry 4 (I think) it's rapid fire and uses powerful bolts.
Kann man das irgendwo kaufen wenn ja wie viel kostet das
I would like to see a self loading prototype either motorized or air powered .
That's what I want, I've got a design in mind that can be made from sheet metal but its going to need some more design work. I'm not sure what people would be willing to pay for one (it won't be a super cheap $100, but I think $300 would be possible), and scalable from 1 motor up to 4, however I'm not seeing high power brushless motors like I wanted to use because I want some insane fire rate with lots of power. What I'm looking at would probably be semi-auto with up to 2 shots per second depending on draw weight.
This example so far has raised over $1500, and its barely been out, so considering that I could probably do similar in a week that's really not bad. If you think a lot of people would want to buy a full auto electric and could sell at least 1000 units (otherwise the cost is going to be pretty high for reasonable profit) then I could spend some time and resources making one.
For you Non-Germans who wonder why it wouldn’t be a weapon in our law if the lever lock weren’t there:
Without lever lock there is no energy saved and stored by itself, just like with an arrow which you need to hold to preserve the energy, thus the ingenious idea with the pinky assistent which holds the lever in place.
It wouldn't be weapon according to Polish law also (crossbows are treated like firearms, more or less) wich is just brilliant!!
So, trollish good looks and strength, reflexes like a 300 kph cat - driving his wife's Porsche on the Autobahn, gifted inventor, world traveller, a laugh that should frighten creatures from bad places and stupid. Hmmmm. I'll buy the first six, but the last doesn't seen to fit at all. More like you like to "do it the old fashioned way"- with your hands, I'm thinking. BTW, another great, true addition to the Slingshot Channel! FR
Amazing! Love watching the ingenuity.
That is next level 3D print design, cool!
Real life Maula Pistol out of Dune!
Next week the full auto version
Turn the pinky holder into the whole finger grip side and add a thumb loop or heavy tail on the backstrap for rapid fire.
It's visually reminiscent of the N7 pistols from Mass Effect 👌
YES! I will be printing one of these soon.
Joerg is the 3D printer! Hahaha
Very nice crossbow pistol, a full size crossbow with a magazine would be even nicer Thanks
You always find the coolest stuff. 👊🏻🧡🇨🇦
That's a cool design. Compact enough to go into a sling holster 😊
Joerg, the other day a thought came to my mind of a device to help loading crossbow. Imagine a standing "rack" in wich you can push your crosbow with your bodyweight and the sides of it "squishes" the crosbow arms, hence helping in the cocking process.
I would love to see post-apo tv show or webseries, where one of the characters or several characters would use Joergs weapons to fight enemies. Some of them may even have 3D printed versions, some of them just made from scrapwood. It makes more sense than normal weapons because ordinary "heroes" usually don't have access to those (unless you live in the USA I guess)
In terms of target shooting, this very good. However, there is one thing that could be potentially improved. That would be where the sights are located. Having a sight on a moving part could be a bit of a problem when trying to adjust it, because there could be a chance it does not sit in exactly the same position. This is why target pistol sights are not located on the reciprocating slide (or bolt, or whatever; reciprocating mass is what it is) and is instead located on top of a piece that sits just above it. This prevents that from being a problem. However, given this is not semi-automatic, and that basically the whole bow is what reciprocates, I suppose that isn't much of an issue at all. This really is a good design.
You are mistaken. The "moving part" also contains the arrow groove, which is the "barrel" of the weapon. Therefore it makes total sense to attach the aiming device to that part.
@@Slingshotchannel Well, ya got me there! Again, this design is wonderful, Joerg!
I just got a printer… still ironing out print quality… this is dope!
