About this 3D model

Derived from 84047 Rock Chucker tray. Removed the ring that went around the vertical ram, so nothing interfers with finger access to the shellholder. Put a spent 22LR case in the small hole, to pin the holder in place. RCBS has a matching hole in the press frame, on the righthand side. Prints flat on table, with support in the tube feed. Punch out with a screwdriver, then clear with a 3/8" drill bit (handheld!)
