Sewing guide to sew straight lines with a hole for a magnet with 18mm radius and 5mm thick
I added the fusion 360 file and you can go back in history and change the size of the hole sketch and how much you pull (for the magnet depth)
The author remixed this model.
This sewing guide has the magnet closer to the needle since most of the metal on my machine lays there and it's meant to fit a 18mm radius and 5mm thick magnet
