For maximum strength up to 50 lbs, make sure to print the hook on its side so that the layers print vertically. If printed upright, the weight of the backpack will fracture the print layers, due to delamination. The backplate is printed lying flat and glued on to the back of the hanger using super glue or gorilla glue to further prevent risk of fracturing.

When assembled, attach to mounting points using wall anchors and drywall screws. Use flat screws to provide a sleek, countersunk finish. I printed this model using a Bambu Lab P1P with default settings with supports enabled.
