I made the base design in solidworks, exported as STL. Imported the STL in MeshLab to create the voronoi pattern.
Printed on my M200 using these settings:
Material: Z-ABS, black
Layer height: 0,29 mm
Support: 10 degrees (20 degrees would probably have given a cleaner print, but that would have been a real pain to remove). I used support lite.
Total print time: a bit under 20 hours
The height of the stand is about 20 cm and it is about 11 cm deep so the ear pads of my headphone fit.
