Beeing the Smartass, that i am, I tryed to print the Bowarms in ABS and in ABS-GF... both trys failed. The ABS did a good job for like 30 shots, then broke apart. The ABS-GF already snapped on the first try to cog. So dont be a Smartass like me and trust the Creator. XD

XD 😂😂thanks with you fail it’s good to know 😂I try with PA CF but I don’t win to print it 😭

Replying to @.O.J :

yeah, i had some spare ABS, so i gave it a try. I made the body in ABS aswell but i had some Warping issues, which only caused some minor optical issues. To compensate for that i added some Paracord-wrapping and a Handle on the Front. Turned out quite nice. https://makerworld.com/en/models/582374#profileId-503501

@user_1492791003

@.O.J

ok why not, which type of file do you need ? STL or other ?

@user_1492791003

Replying to @.O.J :

в ncc вроде. stl тоже открывается

Where do I get the trigger parts? I was unable to find anything online that looks like the pictures above.

Bonjour, je viens de finir de l'assembler et pendant la phase de bander la corde pour faire un essai de tir je n'ai pas pu aller jusqu'au bout car l'arc s'est rompit avant. Je ne comprends pas pourquoi j'ai respecté les recommandations lors de l'impression des pièces et j'ai utilisé tous les liens afin de commander le matériel annexe (corde mécanisme boulonnerie). Et pour ce qui est de la corde je n'ai même pas été jusqu'à 15 tours. c'est dommage

The designer has replied

@.O.J

bonjour je suis vraiment désoler de voir ça mais ça dépends énormément de la qualité du PETG utilisé et également des bon réglages débit/vitesse de l’imprimante.

@angel54180

Replying to @.O.J :

Bonjour, je ne comprends pas non plus pourtant la marque du filament en question est du polymaker (polylite PETG) qui me semble être une très bonne marque. Concernant l'impression je n'ai jamais eu de réel soucis sauf sur la partie plateau / adhérence mais rien de bien méchant. Je suis quand même surpris que le PETG puisse se courber autant sans problème car il n'est pas censé être aussi souple. je retenterais l'impression de l'arc avec une autre bobine en espérant que sa corrige le problème. Échouer si près du but c'est rageant.

@angel54180

Replying to @angel54180 :

Je vais peut-être dire une bêtise mais au lieu d'imprimer l'arc avec du PETG pourquoi ne pas l'imprimer en TPU? il supporterai davantage les contraintes de la corde non?

Petg, %100 infill and broke while tryin to install crossbow rope

The designer has replied

@.O.J

dude you put the bow in the wrong direction ???

@endodent

Replying to @.O.J :

no I put it upside-down for the photo taking, the boroken part rests on it

@.O.J

Replying to @endodent :

if i say it’s the wrong side that’s because it’s the wrong side… And up side down won’t change anything.

What a fantastic model! It all went together as described and works great. I'd like to suggest a couple improvements you might consider in the future: 1) it would be nice to have the two halves latch together with a release for when you need to draw the sting back, and 2) the hole in the rear sight for the adjustment bolt needs to be a longer slot to allow proper sight adjustment. This is an easy fix I did myself with a drill, but would be nice to have the proper size slot as printed. Thanks!!

The designer has replied

@.O.J

Nice thanks 😊 really sorry but I translate your comment and I’m not sure to understand all. Can you explain more with picture pls.

@srgaboury

Boosted

Replying to @.O.J :

Here are examples from a commercial crossbow. For the rear sight photo, you can see a slot is needed (circled in red) to allow proper up and down movement as the sight angle changes. For the second photo, this is just an example of a latch that keeps the crossbow closed during use and is released to pull the string back. Hope that is more clear.

@.O.J

Replying to @srgaboury :

oh ok I see, good idea thanks 😊

@Keltoi

That looks like it's modelled on the Barnet Commando. I own one of those

The designer has replied

@.O.J

yep that’s it 😉☺️

@Keltoi

Replying to @.O.J :

I have a spinal injury. I bought this model specifically to avoid the strain on the back. Great model!

@nextlvlroy

so which plate has the parts to print in tpu? I'm a bit confused. sorry

The designer has replied

@.O.J

my bad I Forgot the print profil, I add it in few hours.

@.O.J

it’s good ✌️

@nextlvlroy

thank you so much! just one more thing, and I'm sorry for asking a lot already, but is there a guide or video I could follow to build this? EDIT: nvm,found your YouTube channel with the video. thank you!

A truly beautiful design I will likely only print the bow for a similar project Have you measured the tension Is it realistic to expect 80 lbs of tension I am confident the release mechanism is printable The one ordered from AliExpress is certainly easily copied Have you tried

The designer has replied

@.O.J

Thank you! That's great, feel free to show me your project's progress 😁 Regarding the tension, I'm sorry but I have no idea, it's sufficient for fun or risk of injury but it's clearly not as powerful as I'd like. Yes, the trigger mechanism is easily 3D printable (I'm currently using it twice as large and doubled for a 3D printed airsoft project) but I didn't want to upload the file because I think a single mechanism at its original size is too dangerous as it's much less robust

Replying to @.O.J :

Thank you for your response! I am always pleasantly surprised when I manage to interact with someone who takes the time to reply It humanizes things I will certainly follow up My project is simply to make a crossbow from the stock of a rifle I no longer use because I replaced the stock with a military model on that weapon A small Ruger 10-22

Replying to @.O.J :

Would you be willing to provide a dimension reference for the trigger mechanism? For instance, what is the diameter of that hole in the image? This would allow me to perfectly design the mechanism I suspect it is a hole for 5mm diameter pins but I am not certain
