Desk Shelf!

This is a set of 3d printed brackets to make an add-on shelf for the back of your desk. I strongly suggest printing them with thick walls or 100% infill. The brackets can be printed on an Ender 3. The uprights are designed to use 1 1/8" or 28mm wooden dowels, preferably Oak. The backing rod (optional but nice to have) is ¾" or 19mm. I used some random plywood I had floating around, this was made with ½" (13mm) plywood, but anything will work as it just sits on top of the flanges. The lower brackets are symmetrical, the upper will need a left and a right version, just mirror the supplied upper bracket in your slicer of choice.
