This is a magnetic switch that uses cheap whiteboard magnets and standard #10 hex nuts to work. Demonstration:
I originally saw

from Andrew Klein and wanted to make my own. I saw other users such as
https://www.thingiverse.com/thing:3556210
had the idea to use standard nuts so it can be assembled at home easily.
This design takes it a few steps further by using space more efficiently to allow more magnets and therefore larger magnetic fields, an internal locking feature, and a snap-fit assembly made entirely of 3D printed parts.
I recommend using a bench vice to install the press-fit part, make sure it is fully seated.
Required Materials:
12x #10 Hex Nuts

The provided g-code prints the handle body with supports, this isn't necessary and it can be printed without them if the orientation is reversed.
If you make it post a picture!
