Compound Planetary Gear

Compound Planetary Gear. Inspired by the innovative designs found on [Gear Down for What](https://www.thingiverse.com/Gear_Down_For_What) and the engaging content on [GDFW youtube](https://www.youtube.com/results?search_query=gear+down+for+what). I've also developed an openscad module to create compound planetary gears, utilizing the powerful features of the [PolyGear library](https://github.com/dpellegr/PolyGear). While it may not be a masterpiece in terms of coding style, it effectively produces functional results. This particular compound gear boasts sun and planet teeth combinations of s=[11,15,11,12] and p=[13,11,13,14], which yields a remarkable ratio of 28.4 and 1134.5 for the second and fourth stages when the first and third rings are stationary. It was created using an earlier version of the openscad code, resulting in some slight differences from the final product. Notably, this gear has been thoroughly tested with a drill and has printed successfully. Additionally, a python function is included in the github files to conduct an exhaustive search for gear ratios and identify sun and planet teeth configurations that meet specific criteria.
