Libra Double Barrel airsoft 40mm shotgun/grenade launcher

The Libra

Classic break action shotgun, in 40mm form! Compatible with all standard 40mm airsoft grenade shells.

All build instructions and files are below, including .f3d and .obj files for that sweet, sweet remix culture. In addition to the printed parts, you will need a couple 5mm rods, like these or similar, and two small springs for the firing pins (the ones I used were about 12mm in diameter)

Edit: added step files!
