3D printed optical rotary encoder using cheap 3d printer.

It cost you almost nothing if you have the optical sensors ..

Rest of the components are just cheap.

I prefer you use small metal balls .. I don't have it so I printed them. But using small balls might make the clicking-mechanism smoother.

Step 1: 3D Print the Parts

Print all parts as shown .. Don't print the sensor :)

I have the files at

You need a spring and some glue and screws.

look at the video for more info.

Let me know if you like it.

thanks.
