My version of a volume mixer for the deej project, uses a 4 linear potentiometers, 1 rotating potentiometer and a arduino nano with usbc.

I added knobs for the linear potentiometers.

I printed the case in Bambu Pla Sparkle Black [https://eu.store.bambulab.com/collections/pla/products/pla-sparkle?variant=43959190946011](https://eu.store.bambulab.com/collections/pla/products/pla-sparkle?variant=43959190946011)

and the knobs and rails in Bambu Pla Metal Gray [https://eu.store.bambulab.com/products/pla-metal?variant=46797850902876](https://eu.store.bambulab.com/products/pla-metal?variant=46797850902876)
