Reloading die lock ring. Works for all dies with standard 7/8"-14 thread. I'm using these in Lee dies and RCBS dies with damaged brass set screws.

Print vertically with supports turned on so the thread comes out well, I used 15% ZigZag. Remove all supports and tap M3 thread through the split hole, then use a 16mm M3 screw to tighten the clamp. M3 equivalent inch-size screws and tapped thread will surely work too.

Scale the part in Cura until it fits easily on your dies and screws on with slight resistance. I had to scale to 102%, but that may differ based on your printer and settings.
