Slide Rubber Band Gun
thingiverse
Simple, Sleek, and Sexy, this simple guy has a capacity of 5 shots, and the whole thing is only 4 pieces with only one tension spring (or rubber band) to make it work, just dab a little glue in each divot on the body and slap together! (never tested, but is simple enough that I reckon it'll work!) Bottom Mag isn't just for show, glue 2 10mm magnets positive to negative (one to mag, one to body) prior to assembly and the hollowed out magazine acts as a convenient storage for additional bands.
