This is a functional zero-button USB trackball. Click with your keyboard or some other way.
It was made using:
- a 38mm billiard ball
- PMW3360 optical sensor
- the PCB from here: https://github.com/jfedor2/rp2040-pmw3360
- 2.5mm zirconium oxide (or silicon nitride) bearing balls
- M3x4 screws for mounting the PCB
- M3x12 flat head screws for assembling the case
- a USB cable
I printed the parts at 0.20mm layer height, they don't need supports.
