Printing:
No supports needed, infill shouldn't really matter too much. If you're using the embedded magnets, just make sure to add a pause right before it adds the top layer, insert your magnets and then continue the print.
If you're having issues with adhesion to the magnets, you can add a bit of gluestick to the top of them.
The author marked this model as their own original creation.
