This model is made up of 6 piramids that can combine to be a cube or a dodecahedron. I'm really happy with the hinge design and clasp. 

To make this you will need to print one of the ‘Clap’ part, 2 of the 'Dodeca Cube' parts, and 3 of the ‘Dodeca Cube Mirrored’ parts. They clip together like in the picture. Alternating mirrorred with non-mirrorred. 

I printed mine at 0.2mm layer height in PETG. PLA works fine too. 

Now with stronger hinges and improved parametric file as of 23/03/2025.
