12 Sided Dice - Keychain - Charm - Stress "Ball" - Dodecahedron (STEP included)

A 12-sided dice as a keychain or simply as a little stress "ball" to squeeze (if printed from TPU). The keychain Version has a central hole 6 mm in diameter for threading a cord through.

As I couldn’t find a perfect 12-sided dice as a STEP file here, I asked ChatGPT to create one for me.

This AI generated perfect dodecahedron in STEP format can also be downloaded here as a raw file so you can use it for your own projects.

It only requires 7-9g of filament.
