Rifle Barrel

A very simple rifled barrel. This could be used for anything. A prop for a realistic gun barrel, or a dart gun barrel coke; to give a soft projectile spin. I printed this out PETG, but you could use anything for your projects. Inside barrel measurements bottom of the groves 17.90mm top of the groves 16.78mmOutside barrel measurements diameter 19.64mmLength 101.00mm
