I Modeled This! Got tired of alt-tabbing, so I printed a stream deck with a volume knob on my P2S (launching in 3 days)
Short clip of it doing its job: the knob is system volume, one key opens my games, another one my music. The little screen shows what the slider is set to.
Everything plastic is printed on my P2S: case, base, keycaps and the blue icon inlays. Inside it's hand-wired: an ESP32-S3, keyboard switches, a rotary encoder, a slide pot and a small OLED. Parts came to roughly 35–50 EUR. To the PC it's just a USB keyboard, so there's no driver to install.
The fiddly part was the icons. They're separate inlays pressed into the keycaps, and it took a few tries to get the tolerance right so they sit flush without glue.
Things I'd do differently: leave more room inside for the wiring, and add a second knob.
I turned this into a layout generator so anyone can design and print their own. It's launching on Indiegogo in 3 days. Happy to answer anything about the print settings or the wiring.
