This is a customizable replacement foot for plastic storage shelves.
The default values are for my Costco storage shelf and are tall enough to fit my Neato vacuum under it.
I didn't think of it before, but you could modify the scad code to act as a riser instead of a replacement for the foot, that way you could save material.
