Sized to fit my number 3 sizing head found here - https://makerworld.com/en/models/525268

Uses 8x2mm Magnets, - Be sure to use the magnets in the BOM as they were tested and work properly.

Magnets in total for the build - 8x2mm = 48 in total

Use Super Glue "I use the gel kind" when inserting the Magnets, and Eye Lens.

Enjoy
