I wanted an X cover that was not a slip on but could not find it, so I duplicated the stock one. I measured the stock injection mold and made this. I have never made anything from scratch before so please keep that in mind when you guys start roasting me. The screw holes are just a tad tight and will need to be threaded through, but not in a way that will pull plastic into the threads. Also be nice to the small mounting post for the micro switch. This was designed in Tinkercad. I have used this on my own Ender 3 Pro and Ender 3 V2.
