Description
Hark! A new project appears on the horizon! Dungeon Blocks is the latest and greatest 3D printing Kickstarter from Zheng Labs! Give it a look and spread the word!
http://www.zheng3.com/2012/05/15/the-penny-catapult/
Here's a basic torsion catapult. It uses one or more elastic bands to launch a U.S. penny if you print it at 1:1 scale. You probably won't get enough torque to be impressive with fewer than 3 bands.
Penny not included!

This is the base broken out of the Zheng3 Penny Catapult. This model doesn't contain the throwing arm. <a href="https://cargames.one">Car Games</a>
These are all very valid concerns! Some of them have been addressed in the updated catapult, part of the Seej Starter Set. https://pinshape.com/items/4097-3d-printed-2013-seej-starter-set
If you raised the whole thing up higher onto a platform or something and added a guide of some sort for the arm the arm wouldn't hit the ground during launch and would result it much better performance.
I agree. Some way to stabilize the main firing arm would be great too. The only thing holding it in place is the elastics and as a result, it tends to move side to side a lot.
I just printed this off and it turned out great as expected. I am just wondering the best way to rig the elastics to work with this. Do you have another picture or any tutorial on the best way to do it?
