Product Description
FOR USE WITH MY OTHER PRODUCT: Platonic solids kit, bar 50mm x 6mm
The knuckle is 6mm diameter on the outside (approx 4.6mm inside).
12 of these make the corners (vertices) of a icosahedron (platonic solid with 20 triangular faces). Add 30 bars to make up the frame of the model. Knuckles and bars have a nice push fit. The dodecahedron is around 135mm diameter.
