Rock Chucker Primer Guard

thingiverse

I built a tiny barrier to stop spent primers from slipping into my Rock Chucker's universal primer arm when de-capping. I would then have to try and scoop them up or place the trash can underneath it to catch them as they fell. The shield is compact (35mm X 20mm) and fits snugly in the slot where the primer arm resides, held firmly in place by the arm spring. Its curved shape redirects the primers sideways when they hit it, causing them to drop into the catcher tray. It works flawlessly and printing out is fast and inexpensive.
