3D printable partial Antikythera mechanism

""" In its current form contains:

    a solar calendar (365 ¼ days) “date pointer”
    position and phase of the moon mapped relative to the ecliptic (zodiac) “moon pointer”
    position of the sun mapped on the ecliptic (zodiac) “true sun pointer”

For V1 I've omitted the entire rear face. The original included the metonic cycle (ancient 19 year/235 lunar month calendar) and the callippic cycle (76 year cycle extending the metonic cycle), the olympiad (4 year games cycle), the Saros cycle (predicts occurance of solar and lunar eclipses in a 223 lunar month repeating cycle) and the Exeligmos cycle to compensate for the 8h offset created by each successive Saros cycle to accurately predict the time and position of potential eclipse occurrences.
