This is a latch (circled in red on the second photo) for the sunglasses holder on the Alfa Romeo 159.
It just clips into place. To get the old one out insert something fairly flat in next to it down to where you can see the bit of round clip/pivot point and then twist until it pops out.
Mine broke at the tip and I could not find the piece that broke off so I did not have the exact measurements, but through few iterations I think it fits fairly well. The replacement seems to work better than the original one which would sometimes get stuck.

Print with ABS or similar, due to high temperatures that can develop in a car during summer. I printed the replacement with nylon.
Supports are needed due to protrusions on both sides of the latch.
