USB Media Dial 3D Printing Projects

This is a USB HID device that is set up to play media and adjust the volume of your speakers. Underneath the knob is a NeoPixel strip that changes color whenever it’s turned up or down.

You can single-click to play and pause media, double-click to skip to the next track. If you long press, it’ll mute the speaker's volume.

The electronics are housed in our 3D printed snap fit enclosure that features a new design. The knob features a built-in LED diffuser with textured knurling on the outer edge.

We used the filament swap technique to make a multi-material print so there’s no need for a multi-extruder. Just use white PLA filament to diffuse the LEDs.

Code, libraries and assembly instructions are documented in the project Learn Guide links below.
