Mini pocketwatch keyfob (single extruder multi-material)

Designed to be rotated face down so you can print with a single-extruder non MMU machine, making a handful of manual colour changes using the M600 gcode command. I've written up that process on another of my designs.

I printed with a 0.25mm nozzle but I think you might be able to get away with 0.4mm.

Works really well with PETG on a textured sheet.

Design is open source (CERN Open Hardware Licence, but printables doesn't have that in its list) and available on github as part of a larger clock project: https://github.com/MrBunsy/3DPrintedClocks/blob/master/toy_pocketwatch.py
