Engraved d6 dice & print-in-place spinners. Export a print-ready STL.
Engraved into all six faces, opposite faces summing to 7. Ink or paint the recesses for contrast.
Prints as one piece and spins straight off the bed — no bearing, no assembly. The center grip is captured with clearance gaps.
Clearance is the gap that lets it spin. 0.4 mm suits most printers. Too stiff? raise it. Wobbly? lower it. A quick twist frees it the first time.
Body color & numeral/grip color. (Both print as one object — color is preview only.)
