d20 box dice holder with correct number pattern

Edit 09/04/2020: adding 0.10 mm depth in the magnet hole.

I was searching for a dice box and print this model : https://www.thingiverse.com/thing:1610141.

However I did not like the numbers and wanted them on a correct placement. So I redesigned a box from scratch.

You can had magnets 7mm x 1mm to close the lid.

I printed those files and they printed correctly with the opened side the plate.

I also printed a 200% version, however you may want to had some support with this size.
