Heavy Duty Wall Hook

My attempt at a simple but strong wall hook capable of holding anything that drywall anchors can. I used Simscale to reinforce stress points. Designed with no abrupt angles. PRINT ON ITS SIDE to ensure stresses are not along layer lines. Best printed in something other than PLA, namely PETG, Nylon, ABS, or ASA. Larger nozzle sizes are ideal for strength. Recommend at least 4 walls and 30% infill for peak strength. Takes 20-30g of filament depending on settings. Published in the Public Domain.
