I spent a week designing this for myself since the guy who is selling these in 4140 steel wants $150 for them. Works fine with PLA/PLA+ for about 50 rounds before softening and deforming to the point of malfunction, but you can print as many as you want so no problem there. I reccomend using PPA-CF core or something similar if you don’t want to keep replacing them. If anyone has any questions on how to use it, hmu
