Armanov 9mm OAL Checker
thingiverse
Instead of buying the Armanov OAL Unifier for the 9mm Ammo Checker, I figured with a 3D printer, I could just make my own version. Just set this under the checker when it is loaded up with rounds and any that are seated too short or too long will stand out against the rest. It fits within the nice storage case that the checker comes in.
