HOW-TO
How to generate a dice STEP / STL file

- 2Adjust corner radius and pip size.
- 3Check the spec cards and any warnings.
- 4Download STEP, STL or 3MF — or send it to Orinovate for a quote.
The standard d6
A cube with 1–6 pips per face and opposite faces summing to 7. Pips are spherical recesses 0.7 × the sphere radius deep, and all edges are filleted by the corner-radius percentage.
Size tips
Board-game dice are 12–16 mm; casino dice are 19 mm with sharp edges. An 8–15 % corner radius feels best. The tool warns when pips are large enough to overlap.

FAQ
How are the pips arranged?
Opposite faces add to 7: 1–6, 2–5, 3–4. Here 1 is on top, 6 underneath, 2/5 front and back, 3/4 right and left.
Are 3D-printed dice fair?
Pips make high-number faces slightly lighter and FDM infill can be uneven, so there is a small bias. Print at 100 % infill or fill pips with paint for better balance; for casual games it is fine.
How do I colour the pips?
Fill them with acrylic paint and wipe the surface with an alcohol-damp cloth, or use a filament change at the pip depth in the slicer.
Which software opens the dice STEP file?
STEP (AP214) opens in Fusion 360, SolidWorks, FreeCAD, Onshape and Rhino. STL / 3MF import directly into Bambu Studio, PrusaSlicer or Cura.

About STEP / STL / 3MF / DXF
- STEP (.step / .stp, AP214) keeps exact dimensions and surfaces for editing in Fusion 360, SolidWorks or FreeCAD.
- STL and 3MF are triangle meshes that import directly into Bambu Studio, PrusaSlicer or Cura.
- DXF is the top-view 2D outline, ready for laser cutting, waterjet or CNC routing.
- All models are in millimetres at true scale.
