About this 3D model

Just some simple legs to lift some of my shelves off the table. Can be uses with anything that has 90 degree corners i guess. Was hoping someone popped one of these up on Thingiverse but since its not yet up, here's one in case anyone needs a quick fix. This one elevates my shelf 25mm off the table top and has a 6mm grip to hold onto any 90 degree corners.
