I've wanted to make this clock for a few years now and finally got a round to it.
The 3d model has 3 parts, the ring, the connector pin, and the diffuser. You'll need 3 of each and maybe an extra diffuser.
Parts were superglued together.
This isn't a very polished model, the cutouts in the ring (for hanging) aren't centered in the segment. There is no specific place to glue in the diffuser. But it works.
Wired with a Pi Zero W and 60 lights per meter neopixel strip. So, one meter. Took several test prints to get the correct circumference right for 1 meter.
Code was a mashup of a couple of digital clocks, plus some original stuff.
The author marked this model as their own original creation.
