Custom version of the Fabric Face Mask Clips. https://www.thingiverse.com/thing:4496809

There are three improvements.

Ver1.0.0

• Resize the magnet mounting part so that DAISO's 13mm neodymium magnet, which is easily available in Japan, can be inserted.
• By making the magnet mounting part circular, you can add an angle.
• The joint between the magnet mounting part and the plate seemed to be weak, so I added a little thickness to the joint.

Ver1.0.1

• Improved to make it difficult to remove the string.
• The joint between the magnet mount and the plate seems to be weak, so I made the joint thicker.

Ver1.0.2

• By shortening the hook spacing, it is difficult for the mask string to come off.
