About this 3D model

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 as recover spring of the hammer.Finally use a ballpen spring choped in two to put the big part (21mm) inside the barrel hole and the rest in the trigger.Visit Rbguns.com, a great site from the very creator of this devices to learn about the assembly.https://www.youtube.com/watch?time_continue=1&v=VGB8zGlMBJw
