This is an electric wool winder driven by a brushless DC motor, controlled by an arduino. A rotary encoder sets the speed and the display shows it and the number of revolutions made. Clicking the encoder stops is and long-press resets number of revolutions.

I printed everything with PETG and thick layers without support, the gears might be quieter if printed in nylon.
Since I didn't make clear assembly instructions here is a larger cross section image which shows how parts fit together: https://i.imgur.com/F7jJ70O.png
