After recently getting into an accident that reduced my mobility, I could no longer access my bathroom towel rack. This double-sided hook is made pretty sturdy, and can fit onto any glass shower door or unit that is about 10 mm thick, as the slot was made 12 mm wide.
I used a 0.4 mm nozzle, 0.32 mm layer height, 0.48 mm line width and 20% infill.
