airsoft 40mm grenade cap

thingiverse

a simple cap for airsoft grenades like the XM-PB4 from Madbull and all its copies. no support required, no raft required, but you can put one if you want. PRINT IN PLA. this is for airsoft. chances are you're using grenades outside, where BBs and parts like this aren't going to be picked up. PLA is bio-degradable. Bio-BBs are made of PLA. don't polute, keep it bio, and have fun!
