Magnet Pin

I don't like using glue on magnets; the magnet always gets lost. That's why I created this design where the magnet is placed inside the model, and there's no need to pause the printing.

I had some spare magnets, 5 mm by 2 mm. The idea is that you can fit two of these magnets inside the print so they don't come out.

You can remove the magnets one by one by pushing them out through the side hole.
