During the development of the Cooler Master MasterBox NR200P, we created several variants for the case feet design.
Following numerous iterations, the launch design was chosen, but we thought "why not share the iterations with our users?"
The team unanimously agreed with this direction :)
As a result, end users can 3D print a selection of different shapes and sizes, and even choose the color based on the filament they print with.
