6 sided LEGO compatible dice.
6 side DUPLO compatible dice.

Print instructions

Dice faces can be printed without any support.
There are two versions of the dice faces: raised and holes.
I designed it with raised and after I printed it I realized that it does not work that great as a dice; so I redesigned with holes. I included both just in case anyone wanted them.
STL files are standard LEGO size.
G-Code files are 2X and therefore DUPLO size.
I have found that designing them at LEGO size and then using 200% in the slicer works the best.
The center (base) should be printed with "supports everywhere" due to the geometry.
