Flexahedron Rehinged

Remix smaller (40mm/side) with screw-secured hinges instead of snap-fit hinges.

To make, you will need 12 of each part (prism and hinge) and 24 screws, M2 x 20mm. I used 20 hex cap screws (all I had) plus four slotted head screws.

In the photos, you can see the lengths of filament I used as hinges before I found the slotted head screws: you could just jam filament in there and cut it off.
