Endstop holder mounted at a 90 degree angle. I made this to mount the endstop using the slots on my custom 3D printer that uses rather unique extrusions, but if it doesn't fit typical extrusions, it would be simple to modify. I included the Sketchup file if you want to modify it.

I just mounted the the endstop upside down as pictured since it makes a nice flat surface that way and you don't have to worry about the solder joints on the plastic side. Works well for me, hope it's helpful for someone.

Printed flat and didn't need any supports. 20% infill since this doesn't need to be particularly strong. It does have some braces to strengthen and seems quite rigid.

These are the endstop I used Amazon I'm using #6 screw/nut for this since SAE is cheap here, but should fit M4 as well.
