Office Catapult

A little gadget to shoot paperballs towards your colleagues. No ruberband needed. When assembling, glue spring part to frame with superglue. I used brim for all parts and shafts was printed upright position. Support is needed also. Some sanding is needed to fit shafts and stem.

How to use....press your index finger into the groove, place the projectile, bend stem, aim and release :D
