Love the OG design but the 6x2 magnets I have laying around didn't have enough strength slid into the slot side by side so I designed this to be able to stack 2-3 magnets for increased strength. It didn’t really make a strength difference and is still fairly weak even with the single layer bottom….
If you end up printing them throw a dab of glue in to keep the magnets from jumping out.
The author remixed this model.
