Post-Printing

Default settings accept a standard 30mm essential oil felt pad. You can buy these online or cut them out yourself.
For hanging, the default settings produce holes for a 7mm jewelry jump-ring. Or wire or thread would work too.

Issues

The first print of this fit perfectly. Then I tried to implement customizer and it was too tight. I think I have it fixed now, but if not, let me know!
You can try the customizer but the larger the image, the more likely it will barf. :_(

Better to just download the openscad file and set a heightmap (or stl in the "hidden" section). Or there is an empty cover stl that you can play with in your favorite 3d program.
