Ill be honest, this is kind of a mess. I wasn't planning on sharing this, so the parts aren't well named... but a few people asked so here we are.

...Plus including the full model, so if you have the know how to cut parts, that might be easier.
parts are sliced to fit on my printer, and they're named numerically from the barrel to the stock. 1.stl, 2.stl etc
sometimes, i found i had to slice a piece again so instead of renaming all of the parts, i just added a dot notation. so for example, part 2 is sliced into 2.1.stl, and 2.2.stl. Im including 2.stl, but if you print both 2.1 and 2.2, you don't need it.
