This works awesome printed PLA at 0.2 speed and and 100 percent size.

Printed in PETG on an ender-3 using creawsomemod - fit is a little loose, scaled the lever 107.5% and it works fine.

Gret model!

Printed it in PLA on an Ender 3 Pro and it works great.

Printed in PLA at 0.2 and works fine.

I'd like to try it in ABS but don't have ABS yet.


Double bonus for the video! Thanks for sharing that!

Trebuchets are the superior race

I printed this with PLA and had to trim some of the ends of the stick like pieces as they wouldn't fit into the grooves. This is with a Lulzbot Taz6. After a little clean up it works perfectly. We can fling pistachios over 20ft with this little womd! awesome. Thanks!

Thanks for the feedback! I was actually considering making a .1mm resolution model with even tighter holes, but it sounds like that will make things only worse for most people. If you have time, please share some pictures!

I have only printed it with abs... works fine :)

Will it work with PLA or will it snap?

Printed in PLA worked great!

I haven't printed it in PLA yet, but I'd wager it would be ok actually. It's not that brilttle! Please let us know if you print it out.

Worked awesome in PLA pretty darn cool! Thanks for the remix by the way, the first one didn't quite work for me :)

Thanks for verifying! Feel free to share a pic if you can
