.22 Magnum Dummy Round

This is the world's first 3D printed replica of a .22 Magnum cartridge, that I designed for a friend's project.
It has the same exact specs as a real .22 magnum, so you might be able to use it as a snap cap for safely dry-firing your firearm, but I haven't tested them for that. I also added a .step file so that you can modify it, too.
