Derringer Rubber band gun

A easily printable version of the derringer rubber band gun from rbguns.com. I have reduced the number of parts and filleted some edges. The barrels have been redesigned to be more realistic adding rifled barrel and a fake safety lever.
The file "Full Derringer" contains all the parts, must fit in a 20x20 cm base. There are separated files for smaler printers.
You can use rainbow loom rubber bands as ammo.
You also need two steel nails 2mm diameter X 24mm long and a 40mm rubber band to use it
