I was inspired by Ian Smalley's clock designs using HueForge and wanted to try it myself with the moon.

This is scaled to fit the Bambu X1C, P1P, and P1S bed. It takes about 10h at Standard speed and I highly recommend you use a brim of at least 3mm, and disable the auxiliary cooling fan or else the side closest to the fan will curl off the bed. I also used some glue on my PEI bed for extra adhesion but it might not be necessary.

You can re-scale the model to fit another printer but don't change the z-height. The center white dot marks the center, where you can either drill a hole or place a negative part in your slicer to form the hole for whatever clock mechanism you have. The one in the picture used a 7.7mm socket.

This is the clock mechanism I used: https://www.amazon.com/dp/B09Q11KHBX

This takes a while to slice so be patient. For some reason I couldn't get it to work on OrcaSlicer but Bambu Studio worked, but it might just be me. I've also included the Bambu Studio 3MF file I used with all my settings and filament changes. I can't include a print profile because MakerWorld times me out for taking too long to slice.
