Derringer Rubber band gun

myminifactory

I've simplified the derringer rubber band gun from rbguns.com for easy printing. I've reduced the number of parts and smoothed out some edges. The barrels have been redesigned to look more realistic, featuring rifled barrels and a fake safety lever. The "Full Derringer" file includes all the necessary parts and should fit within a 20x20 cm base. There are separate files for smaller printers as well. You can use rainbow loom rubber bands as ammunition. Additionally, you'll need two steel nails with a diameter of 2mm and length of 24mm, along with a 40mm rubber band to serve as the hammer's recoil spring. A ballpoint pen spring, cut in half, is required for assembly. One half should be placed inside the barrel hole of the large part (21mm), while the remaining portion is used for the trigger. For further guidance on assembly, please visit rbguns.com, a website created by the very person who designed these devices.
