Strong Hexagonal Magnetic Hook
prusaprinters
This is a very strong hook that can print without supports. There is a hole in the middle for securing to the wall, and a cap which screws onto the front where you can optionally glue a neodymium magnet/s.I printed in PLA with 5 perimeters and 20% infill and it's strong enough to hold a heavy backpack. Also, the top is flat so you can potentially sit something on top (such as a wallet).Print as oriented in the STLs for maximum strength. (Layer lines perpendicular to the load)I used a 32mm magnet, which is incredibly strong. If it's not strong enough for your purposes, you can stack two together.https://www.amazon.com/dp/B093G7WYY9
