Bottle car trunk fixation

I often had the problem that I had to transport bottles and had no possibility to fix them in the car. The bottles rolled around between the purchases and hit one another.
It always took me a lot of time to place my purchases so that the bottles were reasonably safe.

For this reason I designed this fixing. It does not require any attachment points on the car. It is placed only on typical car floor carpets, and is held in place by the weight of the bottles. The typical use case can be seen on the picture.

I tried the fixation with my average defensive driving style, and was very satisfied.

Of course these do not secure the bottles for emergency braking, extreme curves or accidents. The carpet in the used car and the weight of the bottles are the important factors.

This part makes it a bit easier for me to store my shopping.
Maybe another one has similar problems and can do something with my solution.

So of course, use the part at your own risk.
