Lee Die Locking Ring Wrench

Wrench for the newer style Lee locking rings. Fit is pretty tight. If you have problems with it being too tight, bump up the size by a percent or two. It will flex if you try to torque it too much; it's a plastic wrench after all. However, it should work to tighten and loosen the rings better than your fingers.

Print with plenty of walls. You want a lot of material in the jaw area. I went with 75% infill with 8 walls on a 0.40mm nozzle. Perhaps too much infill, but I was trying to keep flex to a minimum. Definitely use the stiffest PLA you have for this. PLA 2 (or the newer less stiff PLAs) will still flex a bit. Nylon or ABS will probably be way too flexy.
