Pea Shooter / Blowgun for BBs

thingiverse

This is a stealthy pea-shooter and quick-load ammo box for plastic BBs I designed for a young friend. Simply suck up a BB, aim, and BLOW! There's a ridge at the mouthpiece end that stops you from inhaling the BB and provides some stiction to keep the ball in place. Lighter BBs work best, and with this setup, I can hit targets 40 feet away or more. To print it, use a raft as the plate contact area is small. After printing, smooth out the bore with a round needle file and then pass it through a scrap of tissue with wax furniture polish to reduce friction further. BBs are 6mm in diameter, just like printer filament is 1.75mm, but they can vary slightly depending on the batch. The shooter will work with any size BB, but getting the suck right may take a couple of test tries. With practice, you could even enter the World Peashooter Championships in Witcham. Safety warning: Never fire at elderly persons, animals, or me unless there's a really good reason to do so!
