Fetched and added all three generated knob models to this project:

Each is Ø18 × 15 mm with a 6.20 × 4.70 mm D-shaft bore. The model cards provide STL, STEP, 3MF, OBJ, and GLB downloads.

I’ll align one knob model to each potentiometer shaft (VR1–VR3), attach them to the board’s 3D scene, and verify their scale, height, and orientation.

Added the three knob models to the 3D preview, aligned over the VR1, VR2, and VR3 potentiometer shafts with realistic materials and full-scale dimensions.

Open the project’s PCB → 3D view to visualize the assembled pedal.

The knob assets are already authored in black; I’m updating the lid and base source materials to purple while preserving their geometry.

Updated the 3D preview materials:

The existing geometry, alignment, and scale were preserved. Refresh the PCB → 3D view if the previous colors remain cached.
