My first functional design. I was propping up an Ikea shelf in my closet with chunks of wood and it wasn't exactly stable. So I designed these little braces to lift the shelf up above the baseboards and fit snugly in its alcove. By chance my set up required I create each necessary variation of cut for the baseboard. 

Built for a .2mm tolerance, the legs will slide in easily but securely but won't be friction fit. 

Panels at the bottom are large enough for 1 inch pads to be attached. I used the squishy kind which ensured it would be level on a hardwood floor.
