I printed a Model S tray for a friend from here: https://www.thingiverse.com/thing:2163325 but I didn't like the original logo that came with it. So I removed it and designed a new one that can function as a pull knob as well. Just attached it with a little PVC cement and it works like a charm.

The photo of the tray was going to be the final print but I broke a section out of the front of the tray AND the logo didn't turn out as clean as I wanted. I guess it's a "working prototype" now.
