3D model description

An octahedron, made of eight triangles sharing twelve edges, four at each of six vertices. Like two square pyramids attached base-to-base. One of five Platonic solids. Midcircles pass through the midpoints of each edge; one circle on each face. Exported from Mathematica in .stl format for smoothness.

3D printing settings

Model dimensions (mm) - X: 40.4, Y: 40.4, Z: 40.4.
Optionally, scale size up or down before you print.
All models in midcircle set have diameter 70mm.

Hi, Dan Bach here. I'm a lifelong math nut, a career math teacher and author, and now a 3D math artist and designer. Download some of my polyhedra or space curves! Print them or use them as assets in your video games. (Disclaimer: I didn't make the big star in the photo, but I had a hand in it!)
