Dry Fire Block for Umarex Colt Commander BB/Airsoft

thingiverse

This handy little piece makes it possible to safely dry-fire your Umarex Colt Commander BBgun without damaging the mechanism. Since all Umarex 1911 style models are based on basically the same design, this might also work for any or all of them, including Airsoft versions. I've only tested it with the BB version, but you can try it out and report back if it works on another model. Print Settings: Printer Brand: Prusa Rafts: No Supports: No Resolution: .2 Infill: 75% Notes: PLA filament works fine, but nylon or ABS filaments would be even better. If printed at 100% scale, this is a very tight fit and works perfectly in my case. You may want to try slightly varying the x or y scale to adjust the fit. Too loose is bad since it pops out when used, but too tight can mean difficulty in removing and you may need a small screwdriver to pry it out.
