About this 3D model

I originally wanted a lanyard to hang my towels, but metal wires tend to rust. Plastic would be a good choice, but there are no such long zip ties, so I chose PETG filament. This is a hook used to fix the end of the filament and hang it on other hooks. PETG has been tested and toughness to be inserted into the curve and compressed. A zip tie can be used to clamp the two pieces together to complete the fixation.
