Galileo Galilei Pendulum Clock (Vers. 3.1)

This is the updated design (Version 3.1) made with OpenSCAD (fully customisable) of a functioning mechanical clock following the original ideas of Galileo Galilei dating back to 1600, that can be made on a laser cutter (with the addiction of standard bearings and a few other simple parts). The previous version is here: https://www.thingiverse.com/thing:5547728

Differences from the previous version:
axes diameter moved from 8mm to 10mm, but small pins are still 8mm;
bearings changed from 608 to 6000 (ID:10mm, OD:26mm, thickness: 8mm);
charge mechanism simplified (one less part);
one vertical pillar removed;
one transfer gear (Z10) removed;
base with rounded corners

The oscillating mechanism uses a clever escapement system attributed to Galileo himself and also the first application of a pendulum to a clock (Galileo was the first to observe the isochronism of the pendulum, in 1602!)

The design has been modelled with OpenSCAD (sources included: two files form the BOSL library are also needed and are included here, just create a folder named "BOSL" and move them inside: constants.scad and involute_gears.scad), it can be animated to show the movements of all parts, and it is fully customisable. Generation of the DXF vector files is easily achieved by uncommenting the "projection" lines and then select "2D export as dxf" within OpenSCAD.

This model is part of an effort, promoted by the "Associazione Amici dell'Orologeria Pesarina Giovanni Battista e Remigio Solari", to teach the basics of the ancient clockmaking traditions of Val Pesarina (Pesariis, Friuli Venezia Giulia region, Italy) to the students of high schools and technical schools in Italy. The model mechanics are based on the original drawings by Galileo Galilei and on many other modern renderings and reconstructions found on the Internet (see source code for links), and have been re-designed in OpenSCAD by Carlo Fonda with contributions from Alberto Tonelli and Stefano Solari.
The prototypes of the various version of this clock have been presented at Maker Faire Trieste, Maker Faire Zagreb and Maker Faire Rome in 2022.

Almost all pieces are made from 10mm plywood, (except two small parts that are from 3-6mm plywood), plus 6000 bearings (ID:10mm, OD:26mm, thickness: 8mm) and wooden axes of 10mm diameter (except the small pins that are 8mm diameter) and few other parts (glue, rope, rubber bands).
The prototype has been done at the Scientific Fablab of the ICTP (The Abdus Salam International centre for Theoretical Physics) based in Trieste, Italy.
