A tool for easily removing the spark plug cap without needing pliers or anything that could hurt your hands. It also includes an M10x1.0 thread on the other end for a CM6 spark plug.  Designed it for a 50cc DA engine, so it should fit several similar engines. The thread is set with a 0.3mm offset; it works well on my Creality Ender 3, but you'll have to test and adjust it for yours. I printed it in PLA with 20% infill, and it holds up well; it doesn't break.
