This is a hit points tracker for D&D / Heros&Dragons, or any game that needs a counter, really :)

It was a great fun to do, and it allowed me to try new things to link the three parts together.

The clever mecanism for controlled spinning of the wheel comes from this other hit point tracker https://www.thingiverse.com/thing:3458256 it is beautiful but I wanted something different.

As usual, I used openscad to design it.

The code probably needs refactoring ! But you can very easily edit it to generate 1, 2, 3 or more digits trackers and change the text displayed on the top part. I generated 1, 2, and 3 digits with french and english text for "Hit points", but you might want it otherwise.
