Pulley for small motor

thingiverse

This is a pulley I designed to pair with a small motor. The pulley fits snugly onto the Mabuchi RS-555 motor, a popular hobby motor commonly used in RC Cars due to its compact size and impressive performance capabilities. This particular motor boasts a 3mm shaft diameter, ensuring seamless integration with various mechanical systems. To bring this design to life, simply print it using either PLA or ABS filament, opting for at least 20% infill density for optimal structural integrity. You'll need three M2 bolts accompanied by nuts to securely attach the pulley to the motor shaft, while two additional M2 bolts will serve as a sturdy link between the motor and its mount. Thanks to my careful design considerations, you can expect a relatively support-free printing experience, freeing up valuable time for post-processing and assembly. The following print settings are recommended: Printer: Prusa I3 Rafts: Not required Supports: Unnecessary Infill: Aim for 20-30% density I created this pulley using OpenSCAD, a powerful tool for designing complex mechanical components with ease.
