Catapult

I did my best to duplicate the genius of Luke Tansell, recreating https://www.thingiverse.com/thing:1763518 in my own CAD software. Improvements include:
* My granddaughters tended to break off the "spoon" end, so I beefed it up
* If my material doesn't string, it's operational immediately and doesn't need to be broken free so that it moves properly, so there's likely more clearance than the original.
* This version includes a little ball to launch with the catapult
