I purchased the following clock mechanism from TEMU and installed it in the print. The sliced model also includes the changing of different colors. I printed it with an Ender 3 NEO printer! The sequence and the color changing times can be found in the photo called prusaslicer. The layer thickness of the gcode is 0.2mm. I made the hole in the slicer by adding the negative volume.
The author marked this model as their own original creation.
