Shape

Choose one of the three regular star polyhedra (Kepler-Poinsot solids)

Core Edge Length 1–300 mm

Edge length of the regular polyhedron before the spikes are raised. The overall size is 1.9 to 5.0 times this value

CAUTION

The regular star polyhedron generated by this tool matches the overall shape of the mathematical regular star polyhedron, but the defining self-intersecting faces cannot be represented as a CAD solid and are therefore not reproduced.

ABOUT · STEP

The STEP file (.step / .stp) is a standard 3D CAD format that retains dimensional and topology data. Compatible with major CAD software including Fusion 360, SolidWorks, and FreeCAD.

Full-scale solid (mm units)
Editable dimensions and post-processing in CAD
Convertible with a slicer for 3D printing
