Tesla Model 3 Trunk Hook

Being a proud owner of a Tesla Model 3, I was looking for ways to improve my car use experience. I do find that shopping bags can fall and loose their content into the boot of the car. Placing the bag into one of the car's bays is one approach, but a trunk hanging hook is a simple approach, too. The Model 3 (and Y) have a protruding M6 bolt which can be utilised for a hook mount.

There are other similar trunk hook designs available for download, never-the-less I decided to create my own design. My design had to meet the following criteria:
- Be strong.
- Be straightforward to print.
- Be able to handle the high temperatures common in cars.

I ended up choosing Nylon as the print filament, though a PETG filament would have been a suitable alternative. Fitted to the printed part is a M6x15mm metal screw insert similar to the following part:
