A miniature digital piano / keyboard (No MMU required)

I made this model as a little additional surprise piece for a gift.

To print this model, one needs a slicer with a color switch functionality, and of course, two different colors of filaments.

Modeled with FreeCAD 0.21.2.

Size

125mm x 24mm x 8mm
