A compact 4×4 macropad for Windows productivity workflows (Fusion 360, Bambu Studio, Adobe Illustrator/Photoshop, DaVinci Resolve). It features two knobs: the left knob is a push-button only (purely for aesthetics), while the right knob is a real rotary encoder for volume control.

The enclosure is designed as five parts:
- Top cover (protects the PCB; acrylic would look great).
- Base (with heat-set insert holes to mount the PCB and top cover).
- Side cover (hides the PCB ; would look great in milled aluminum).
- Sub-base / stand (tilts the macropad at an ergonomic angle).
- Connector (connects the base with the stand).
Firmware is written in QMK.
- Left knob: push-button only → Mute/Unmute.
- Right knob: rotary encoder → Volume Up/Down.
- The 12 keys are mapped to common Windows shortcuts.
