I was looking for a small dice holder to hold one set of dice effectively. This dice holder will hold 7 dice (one full set) and is held together with 12 magnets. This very simple design is very easy to print and will easily fit on almost all print beds.

In addition to the plain top I also added an inscribed D20 version if you should so decide. One comment on this, make sure when laying the D20 lid on the print bed, that you rotate it and look at the print path so you don't have any long bridges across the inlay of the D20, or you will get some drooping

Magnets used are 5mm x 1mm
