These brackets are a direct replacement for the brackets included with blinds commonly found at Home Depot and Lowes. I printed them with the following settings: 0.2 layer height, 0.8 shell thickness, 100 % infill. You may be able to get away with less infill but I wanted to make sure these did not break like the original brackets. I created two brackets one has no sliding panel (v5) so it is stronger. It can be used on one side and the other bracket (v6) can be used on the other side to allow installation of the blinds. The solid bracket should be used on the side with the pull cords for extra strength.
