This is a USB trackball, made using:
- a 38mm billiard ball
- PMW3360 optical sensor
- the PCB from here: https://github.com/jfedor2/rp2040-pmw3360
- Kailh GM mouse button switches (or any other switch with the same footprint)
- this PCB for mounting the switches: https://github.com/jfedor2/mouse-switch-mount-pcb
- 2.5mm zirconium oxide (or silicon nitride) bearing balls
- M2x4 screws for mounting the buttons and the switch PCBs
- M3x4 screws for mounting the main PCB
- 3x10mm wood screws for assembling the case
Only the left button model is included, to print the other one use the mirror function in your slicer.
The top part needs supports, the others don't.
