This date dial complements the Antikythera mechanism model made by FreddyZ (https://www.printables.com/model/284372-antikythera-mechanism).
It can be attached to the front frame using three M3x8 screws. Heat inserts are optional.
Print quality needs to be very fine to capture the text details. Color is changed at about 1 mm height. My print was made on a QIDI Tech X-Max 3 with black and white PLA, using QIDI Slicer with the following settings:
Layer height: 0.12 mm (Extra High)
Perimeter generator: Arachne
Arachne minimum feature size: 15%
Slice gap closing radius: 0.04
The 12 o'clock position is March 21st rather than January 1st to match the model's zodiac dial. This date represents the start of the astronomical year as it was used in ancient times. The transition of the sun from Pisces into Aries also coincides with the beginning of spring and roughly the vernal equinox (in our current epoch at least).
Happy Star Wars Day to everyone btw ;-)
