snap together desktop catapult +
thingiverse
A small put reasonably powerful working catapult made of 4 parts that doesn't require any glue. I've modified the excellent catapult by Julius3E8 as follows: 1 - the catapult arm is now constrained so it doesn't fall out the bottom of the base 2 - modified the firing lever so it now has a spring (end is constrained in the base) 3 - added a strengthen bar to stop the base flexing when firing 4 - reduced the gap between hook and lever so it is a snug fit 5 - modified the catapult arm so it lines up better with the catch when pulled back
