This is a round counter for Dillon 650/750 Reloading press, it could be used to count other metallic items I suppose. Remixed from a round counter for Dillon 1050 reloading press found on the internet a couple of years ago. The counter was remixed to work for the Dillon 650/750 press, increased the caliber sizes to at least .45 pistol/308 rifle, and added an on/off switch.
I printed with supports on bed and upside down, brim is optional depending on material. Make sure no supports in proximity sensor mount, the tap die is to ensure threads work for sensor to screw in with no issues.
Rocker switch
Inductive Proximity Switch NPN NO DC 6-36V Cylinder Type
