From the digital model to a real object

In development. The starting data exist; the print files are in preparation, as described below.

What already exists

30 measured wheels: tooth count, outer and inner radius, thickness and depth (Freeth et al. 2021, Table S8) — the same ones used by the 3D model.
The layout: the axis positions are solved by requiring every pair to mesh (distance = sum of pitch radii).
The complete kinematic chain: every ratio is checked against the astronomical periods (254/19 for the Moon, 940/4237 for the Saros, etc.).

A single module. The ancient teeth are triangular and not uniform; a working print needs redrawn profiles with a standard module while keeping the counts. in development
Tolerances and clearances for FDM/resin printing and for laser-cut sheet metal or acrylic.
Arbors, bushings, plates with real dimensions (the plates at 0, +7.5 and −16 mm are already in the model).
The pin-and-slot group (k1/k2, 1.3 mm eccentricity) and the e3/e4 epicyclic platform: the most delicate part.
Printable dials and scales: zodiac, Egyptian calendar, Metonic and Saros spirals.

Milestone 1 — STL/STEP export of the wheels with a standard module and a simplified frame, with assembly instructions. date to be set
Milestone 2 — educational kit (reduced version: solar-lunar train and front dial) for schools.
Milestone 3 — full model with back dials.
