3D-Printed Servo Motor Has 360 Degrees Of Rotation

Hobby servos are nifty and useful for a wide range of projects. There’s nothing stopping you from building your own servos though, and you can even give them nifty features like 360-degree rotation In fact, that’s exactly what Aaed Musa did!

The servo relies on 3D printed gears in a 3D printed housing. The design makes prodigious use of threaded inserts to hold everything together nice and tight. A DC motor is charged with driving the assembly, as with any regular servo motor. However, in the place of a potentiometer, this design instead uses an AS5600 magnetic rotary position sensor to read the servo’s angle, via a magnet mounted in the servo’s gear. An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.
