Rock Chucker Primer Guard

thingiverse

This is a small guard I created to prevent spent primers from falling into the spring area of my Rock Chucker's universal primer arm when de-capping. I would then have to try and fish them out or put the trash can under it to catch them as they fell. The guard is small (35mm X 20mm) and fits in the slot where the primer arm is, held in place by the arm spring. Its curved so when the primers hit it, they are deflected to the sides and fall into the catcher tray. It works really well and is quick and cheap to print out.
