Desk shelf

In need of a monitor riser which fits a music-keyboard below the monitor I went to the store and wanted to buy some modern simplistic legs. After seeing the price tags I went back home and modeled these legs, supports and shelf spacers. The legs screw in place at the corners. They are designed to be used with 20x4 [mm] wood-screws and a 1.6cm board without the screws poking out the back. If you use thinner material, you should use shorter screws. The support can be used for longer boards to support it in the middle to prevent bends in the shelf. It is designed for the same screws as the legs. The spacer between the shelfs if of course optional. It is designed to be printed without bottom and top layers and with a hexagonal infill pattern, so that the pattern is visible.
