NEMA17 planetary Gearbox

thingiverse

I designed a planetary gearbox for a roller blind with a bracket for ceiling mounting and a body to conceal the stepper motor from view. Additional details and an ESPHome YAML file can be found on this community forum post: https://community.home-assistant.io/t/motor-on-a-roller-blind-esphome-version/116179/73 **Warning:** I strongly advise against simply downloading and printing this design, as there are numerous variables that may not align with your specific requirements. This design was tailored to my own printer's tolerances, location preferences, material choices, and roller blind specifications. This design is optimized for: - The precise tolerances of my 3D printer - Ceiling-mounted installation, which influenced the screw hole placement in the mounting bracket - Reused M4 screws and a cable tray, necessitating a slight adjustment to ensure proper fitment - My specific roller blinds, featuring an inner tube diameter that differs from other brands, such as Ikea - A gear reduction ratio engineered for optimal speed-torque performance
