Simple feet for a box

I needed some simple feet/standoffs for my CaseRap printer case so in transport mode it would not sit directly on the wooden surface and on/off switch. This is my simplest design to date, haha.

The feet will take a 3.5 mm wood screw. The head of the screw will sink nicely into the opening of the feet so not to scratch up any surface you put the case/box on.
