This is a simple printable z-end stop for CNC machines found on AliExpress. It should fit most models like the 3018, 2410 and 1610.
The limit switch I modeled this for has a case size of 11 x 6 x 6 mm (excluding the pins)
- CNC_Z_End_Stop_v9.stl - Added more depth to the limit switch hole so that it triggers higher up
There is a removable 'support' in the limit switch hole so you do not need to print with supports
