Designed these for a friends combat patrol event and wanted to share with others who would enjoy them. These ones are design to hold standard 16mm d6. I have also designed a 11mm 6d version as well which is also shared on Makerworld. You should be able to custom paint them from the 2 to 3 mm height and then from 3.2-3.6mm if you wish to do mulit color. Hope these make your gaming experience that much better.
