BB firecracker cannon (Please comment results as this is untested!!!! It should work well though.)
thingiverse
A 2-piece BB firing cannon powered by firecrackers is currently untested due to a lack of filament but should work well once more is obtained. Load the firecracker into the larger hole on the barrel, screw on the cap while feeding the fuse through the hole in the cap, then load your BB and light the fuse. A carriage/mount for the cannon has not been made yet. You may need to use supports but shouldn't have to, as mentioned earlier, this cannon is untested. Using 100 percent infill is recommended to prevent the cannon from breaking.
