This is a bracket that affixes to the top left corner of a Samsung U28D590 monitor. It has a slot on the back for inserting anything you'd like hanging above your monitor (I have a simple angle bracket for hanging my headphones). The FreeCAD file is included so you can modify it to meet your needs. There's more cut out than is necessary for the monitor because it was easier to model that way, the monitor itself has more curves on the back but the bracket is solid when affixed to the monitor as-is so I didn't think it would be necessary. There's an extra millimeter of tolerance in case your printer isn't well calibrated. I've considered adding an extra half millimeter to the vertical retaining lip on the side but it holds okay as-is. No supports should be necessary as the steepest overhang is only 15 degrees.
