To improve the Z-endstop of the SapphirePro, i designed a model which hits the Z-endstop perfectly every time.

Information
To adjust the height exactly, I designed an endstop where an M3 screw (flat head is recommended) presses on the endstop switch.
to fasten the whole thing, you also need a M3x20 screw and M3 nut.
(in the v6 version this works without the nut)
To achieve more accuracy you can flip the switch around, so the far side of the lever points away from the rod.
What you need
1x M3 x 20 to 30
1x M3 x 20
1x M3 Nut
Versions:
- 8mm Version presses more directly on the switch (like in the picture)
- 6mm Version presses on the lever
- 8mm Version with smaller screwholes
- fusion 360 files to edit anything you want

The idea came from CNC kitchens endstop design
