Desktop Catapult - Mini Rubber Band Catapult Kit with Ammo, No Supports (OpenSCAD)

A little desktop catapult for office battles and kids' science fun: a base with two towers, a throwing arm with a cup, an axle pin and four ammo balls, all on one plate. Loop a rubber band from the notch on the arm's tail round the low bar, pull the cup down and let go: the arm hits the stop bar and launches the ball. Not at people or pets! DETAILS • Base 90 x 60 mm, arm 115 mm long, 12 mm balls. • Prints with no supports: the towers lean at 45 degrees or steeper, the axle holes are teardrops, the two bars are short bridges, and the pin and balls lie on flats. • Bambu Studio: 1 h 30, 36 g for the whole kit. CUSTOMIZE (OpenSCAD) Arm length, cup size, ball size and axle clearance. Designed with AI assistance (OpenSCAD). Rendered images; not printed yet.
