The file 'I3 Adjustable Z-Axis Micro Endstop For 8mm Smooth Rod 3D Printer Model' is (stl,STL) file type, size is 29.5KB.
Designed for the microswitch mechanical endstop. If you are using Aluminum Couplers on your Z-Axis, I'm not totally certain if it will not rub the side of your coupler. I did try to make the endstop holder as thin as possible.
What I used:
3 - M3x20mm & 1 - M3x15 bolts plus washers and nuts. 1 spring inside of a retractable pen that I cut in half. 2 - M2x12mm & Nuts for Micro Mechanical Endstop.
Printed this at 0.2mm layer height with 45% infill. Also with .35 nozzle. It's favorable to use ABS but PLA will work too.
