Similar to my D12 model, I couldn't find a simple 6 sided dice model that allowed for single color print and then some manual assembly. Here you have to use tweezers to place these tiny 2mm dots inside their holes. The effect is pretty rad! I used BambuLabs PLA Matte Black and PLA Silk Copper.

Update – I resolved the issue where dots were on incorrect faces. The photos of the prints won't reflect this, but the 3D files do.
