Summary

Introduction:
This is a mount for a limit sensor that is optimized for a 2020 rail. Several iterations of this design were made to ensure it is fully functional. This mount can be used with either an opto end stop or a conventional mechanical switch end stop provided that it is built by bigtreetech or that is has a 19mm spaced mount. I do not have the specific origin or manufacturer of the opto-switch, but I provided a photo it.

Requirements:
Besides a switch PCB, three M3 cap screws are required along with two nuts (that are pressed into the mount) and one T-nut for rail mounting.

Instructions:
Prints in both .1mm and .2mm, came out good. Suggest cranking up the infill, as compressing the single T-Nut is required to hold this bracket securely.

Other Stuff:
To securely mount this bracket two screws should have been used, but this would have overly complicated this project. There could be other nuances that some may want to change. So the source files were included so that changes or improvements can be made by this community.
