Remixed to use as a clock face or coasters. Keep Z height at 4mm, stretch X and Y to whatever you want or your printer will allow. If printing at 0.2mm layer height, change filament at 12 layers. I have not made a hole for the movement, to allow the design to be use as coasters or other uses that do not include a clock. When installing a clock movement it is best to start with a small drill bit and gradually change drill bits up to the size you need.

How I Designed This

Created a 2mm thick 12 point circle in Tinkercad, added the Ygdrasi; file 4mm thick.
