Fractal Design R4 Wheel

Made this computer wheel so I could roll my computer case around. Works pretty well. The wheel portion is separate than from the stand thing. Basically you screw the stand thing in to the computer case where the rubber foot used to go and then slip the wheel on it. The stand part can be customized to fit any case.

This design also allows any surface to have wheels because all you need to do is drill stand into the platform and then slip on the wheel and your good to go.
