I have found the USBvalve on Github. (https://github.com/cecio/USBvalve)
Its a great project, but i wasnt a fan of the original case for the PCB. So i made my own one. You need the Pi Pico with Type-C, the USBvalve PCB, the OLED and another printed spacer (https://www.thingiverse.com/thing:4748043 ; Not mine, its a bit snug on the Type-C Port, so i clipped off the plastic).
The case bottom is the same for both types of OLEDs, for the top, print either the 128x32 or the 128x64 piece.
The author marked this model as their own original creation.
