Percussion Cap Snapcap
thingiverse
A basic cover for black powder revolver nipples. Dry-firing a percussion cap revolver without a percussion cap under the hammer can cause damage to the nipples, so this provides a safeguard that protects them. This is still a work in progress, the caps only last about 10 strikes each before being smashed beyond repair, at which point they no longer function. I've had more success with ABS than PLA. Currently, I don't have access to other types of filament, but when I do, I will experiment with those as well.
