Cannon for ping pong balls

thingiverse

I Manufacture Ping Pong Ball Cannons From High-Quality Materials: I Produce these units using 4.1mm Medium-Density Fiberboard, but the piece you pull is best made from 4mm birch plywood, even though it works perfectly fine with MDF too! Adding two rubber bands and a ping pong ball creates hours of entertainment for users: simply Have Fun! Assembly Instructions are included in a PDF file attached in English.
