I made this so I could have a shelf in my window for my plants. Remember to also print a mirrored version so the bracket with be facing the right way. The screw holes are counterbored 3/8in and are 1/4in in diameter. The ledge sits far enough out to not interfere with your blinds. The hole on the end is incase you want to secure a plank to the bracket. The pictures are from my second version, this one is slimmed down.
