Triple wall hook 3D printed model that I designed using Blender. We had one hook in the kitchen to hang things up on and we decided that it wasn't enough so I decided to create a new triple hook design. The hook can stick onto any surface with just a simple command strip. Using a command strip may limit you to only hanging light objects. If you need extra strength you can consider screwing it into the wall but that will leave permanent holes. The model was printed in white PETG filament as it is a stronger material than PLA and I was trying to find a use for my PETG filament roll that was almost empty.
