I remixed asb2106's design because the letters aren't fully attached to the baseplate when sliced. I re-created it from scratch by using the original design as a sort of template.

The only extra items you'll need for this print are 12mm x 2mm magnets. The ones I procured for my tests were from this variety pack.

There are two versions of the print available:

• 12mm - magnets should be a perfectly snug fit.
• 12.5mm - magnets fit loosely, so you will need some super glue to keep them in place.

Special considerations for inserting the magnets are below.
