An upright that screws to the wall, an arm that carries the shelf, and a diagonal brace between them that turns the load into compression. Two holes go into the wall and two up into the shelf.
Set the depth to the shelf's depth less a centimetre and the height to at least the depth, so the brace stays near 45 degrees. A bar of 6 mm and a width of 20 mm in PETG carries a shelf of books on a pair of brackets 60 cm apart; widen the bracket rather than thicken it for heavier loads.
The bracket lies flat on the bed, so every bar is printed along its length and the layers never take the load across. Print it with four walls and 40 % infill; no supports.
