I did think of doing that (as well as putting sides on one of the pieces, or notch/tab to prevent lateral slip), but figured it could be an “iteration” along the way because it adds some complexity to the model and tightens the tolerances for how the 3d-printed parts fit together. First thing is to see if it’s at all viable, *then* make it better
[edit] it’s also just occurred to me that I’m over-thinking it wrt the magnets. It’s a mesh. An ‘S’ hook would work, and can’t lose its grip.
