“Most hobby servos are limited to less than 360 of rotation. Let’s fix that! In this build, I’ll show you how to make a 3D-printed servo motor. Like traditional servos, this servo has position feedback. Unlike a traditional servo, this servo has 3D printed gears, is much faster and stronger, and has 360 of rotation. This is quite a simple build. I finished this project from start to finish in a weekend. Let’s begin.
