The MIDI to CV Skull may be assembled with 3D printed plates, described below. The top of the case can utilize a color swap to make the skull art pop. The pieces could also be milled or laser cut from other materials, such as wood or acrylic.
The STL files can be downloaded directly here or from Thingiverse.
The skull art is achieved with different depths in the .STL file that can be accentuated by using a color swap at the 1mm height of the model in your slicer software.
