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.
