Create your Gearset

Key customization options include:

• Gears: Set the number of planet gears, gear thickness, and module size.
• Modes: Configure sun-driven, carrier-driven, or ring-driven setups.
• Details: Adjust handle dimensions, shaft diameter, and optional cutouts for a lightweight design.
• Angles: Choose between spur or helical gears with adjustable angles.

This script relies on the BOSL2 library and particularly on gears.scad for gear assembly. Kindly refer to the documentation for more details.

Print your Gearset

Any default print profile works just fine. For a smoother result, slightly reduce the layer and wall speeds. Built-in clearance using the Slop parameter ensures smooth assembly; no post-processing required.
