Loading and Firing
Here is the ultimate 3d printed rubber band gun. Modeled after a Colt Government Series 1911, the WW3D 1911R prints in place. That is right, no assembly, no glue, no screws. Just remove the supports load and fire. I have included a removable magazine and collapsible targets that fit in the magazine for easy storage. It fires #31 rubber bands so no need to spend money on over priced "rubber band gun ammo".
Below is a link to the rubber bands this is designed for. If you use stronger rubber bands, or load more than four shots it may result in failure of the rotor.

I added a new version with 0.3 mm clearance between the moving parts vice the 0.6mm clearance in the original. Use this version if you think your printer can handle those tolerances, or if you are printing with soluble supports.
*Because this is a highly detailed replica of an actual firearm, only print it bright colors to avoid it being mistaken for the real thing.**
Layer Height: 0.2
Supports: From build plate only, if you are using custom supports ensure to support the rotor and the axle is spins on. Also remove any supports that extend up into the body as they will be difficult to remove.
Orient the model so that the barrel is pointed upward and tilted at a 15 degree angle towards the top of the gun as seen in the picture.
Depending on your layer height, and your machine tolerances you may need to sand the edges of the rotor in order to remove the layer steps and allow for smooth operation.
