In my never ending battle to start more projects than I can ever finish in my lifetime I’ve decided to build a miniature cannon. The bore is 0.375″ and the barrel is about 7.5 inches long.
Made this back when I first got my printer. This is a pla 6 round magazine for an ak47. It’s actually strong enough to withstand the weight of a cinder block. Not to bad for like $1 in material.
