It is a base to attach the rare earth magnets to a CNC machines such as X-Carve or similar when upgrading your machine limit switches to Hall Effect switches.
It uses a screw to hold the magnet to the side extrusions such as the MakerSlides.
I used these limit switches: by Solder/Filament Solutions
UPDATE:
This version decreases the size of the magnet hole to make it go in more tight. And makes the screw hole larger to allow for M5 Screws.
Printer Brand: Prusa
Printer: i3 MK2S
Rafts: No
Supports: No
Resolution: .2
Infill: 50% - 60%
Notes:
I used PLA for my mounts but should not matter, just use care when attaching the magnets not to brake the part.
Since the part is small I used 60% infill to make it strong.
