Parametric magnetic switch

I saw Andrew Klein video, https://www.youtube.com/watch?v=n9tZIFfM14o
and was inspired but being from Europe I needed metric, so I generalized his design from looking at it, using OpenScad. He sells some tested stl on his website, so don't forget to reward him accordingly.

Here are not tested yet (you will need to specify your dimensions and add tolerances) design files to help explore the design space of magnetic switches, with various number of magnets. The hex nut design was successfully printed and tested.

If the scad doesn't render properly (it's bugging on thingiverse thumbnail) increase Preferences->Advanced->Turn of rendering at … elements .

There are some not needed height in the half with round attachments so that the rods are of the same length for the top and bottom, but if you are willing to cut them of different length, you may get a little extra strength, by setting hatt=0 for this half.
