Did this like a couple of days ago. But since covid19, no car and nothing to do, I made this :
It's the trunk tool screw holder thing. My tool box keeps falling off cause the groove in the piece is too small for the thickness of the fiberglass on my CSL trunk. So I just made this and made the groove larger lol I don't have my car to test yet, but at least I got the basic shape and thread sizing down. It'll only take seconds to adjust the groove size and like an hour to print another one if it doesn't fit.
I actually made a few things, but this was the only e46 specific thing. I made a Pi Zero W case the other day. Making a letter opener today :
