[Question] how to make a 3d printed 2x2x2 magnetic-mechanism?

[Filipe Teixeira]

please look at this:

3x3x3 magnetic model: https://www.printables.com/model/632446-magnets-only-3kh3-rubiks-cube-v2/comments

Spoiler

I made my own version of a 2x2x2 based on that project but I faced a problem with magnetic polarity

I understood that on a 3x3x3, because it is an odd cube, the magnets will always atract. but it is not the same for 2x2x2.

my model is basically a cube with 3 adjacent slots for magnets
I print 8 of those to form a 2x2x2



but look at this:



in this simulation I reach a "dead-end". because no matter what movement I do, I will always face a magnetic repel.

Look at this video at 6:49. You need twice as many magnets (2 on each inner side instead of 1) in this configuration. You can ignore the rest of the video, it's about magnetic physical hypercubes.

That way it works!!
