Support for safety net BMW (i)X1

This is a quick fix I made for the safety net that prevents things in the boot of the car flying towards the front in case of a collision (and to keep the dog in the bay). The standard net that BMW sells is of a limited quality, in my eyes, and the upper thicker band of the net blocks my view through the rear mirror. This thing fixes that.
The base can be put under the head support for the middle seat. The stem is deliberately a bit flimsy, so that it does block the rear view in the most minimal way.

It isn't symmetrical, for I wanted it to be easy to print. It doesn't need support, when you place it the right way on the bed.

I have used ABS for this, but PETG should be fine as well. PLA is not advisable, as it can get hot in a car in the summer
