Robot actuator for 28mm stepper
Description
This is a remix of LoboCNC's robot actuators, and this one replaces the 35mm motor for the 40P gearbox with a much cheaper 28mm one. The original gearbox used a 35pm048s8-08001 tin can motor, but it was expensive and hard to find. So, instead, I modified the design to use the much cheaper 28byj-48 motor. Secure the motor using whatever you need to use, whether it be screws or super glue. Note: You may need to cut out part of the arm part, depending on whether the motor sticks out or not. Print the PlanetCluster pieces at 100% scale to reduce backlash and increase stress, or print them at 98% to loosen them, but this will increase backlash. What to print: 1 - Ring48-28mm 1 - Body28mm 1 - Sun15_28mm 1 - Sun18-28mm 3 - PlanetCluster28mm
