The bitcoin wall clock consists of two parts. Printed with:

Voxellab Acquila X2 Golden Silk PLA 60°C heated glass plate (coated with hair spray) 205°C nozzle Room temperature approx. 16°C No raft, no supports Cooling fan manually turned off (to prevent warping).

Diameter of the clock is 22cm (maximum I could print).

It is designed for usual radio clockworks like this one: WWVB HD-1688 i.e. from Amazon, but many others should fit as well.

The digits on the dial are encoded in binary code.
