Cooler Master HAF Foot Stand

Some legs for a Cooler Master HAF 912 computer case to help lift it off the carpet. I originally had the thing on wood blocks but in a bit of irony had to use those to lift my filament box a bit higher for my new Prusa MK3. These look much better than wood blocks (and are a bit higher too).

I measured the feet of the HAF 912 but have included the FreeCAD file if folks want to try making one with a different foot size. It's using CSG of cones and cylinders basically.
