Tested with easy 13
Uses the same connector (I tried the easy 13 one) and toe
I used these feet rather than the original because the original isn't quite big enough to add the magnets to while keeping the connector unchanged
Don't need glue, but the bridging and size means it's a bit finicky to print.

The author remixed this model.
