I made a bunch of tweaks:
- Strengthened the X-endstop legs, as the original snapped when I tried to install it
- Thickened the mounting surfaces to allow more screw engagement
- Reduced the length of the Y-endstop body, as the mounting area on my machine was shorter (~25mm)
- Added threads to the holes for M3 machine screws to secure the endstops. Note: I prefer using M3 hardware; I did need to enlarge the holes on my particular switches using a 3.2mm drill bit.
