My Customized Captive Planetary Gear Set: parametric.

thingiverse

This design of custom gear train was generated using a tool on the website http://www.thingiverse.com, where you can adjust various settings to suit your needs. The settings used for this design were: pad thickness = 4, number of planets in the gear system = 4, style type = 1, number of teeth on each planet = 7, twisting power of each planet = 1, approximate number of teeth on the central sun component = 9, outer width = 6.7 units, primary angle adjustment = 45 degrees, tertiary adjustment setting = 6, and a tolerance value set at 0.15. Secondary depth is configured to a value of 30. This system operates within 5 steps per cycle in terms of step speed and the distance between planet axes measures about 6 units, with diameter measured by the secondary depth (sd) variable.
