I have, problem is that most people that own diesel Mercedes are cheap - that is why many OEM parts are being discontinued. I do not have the $5000+ required to make the tooling for an injection molded pocket, and if I did have that money and invested it into these door pockets, I don't think I would make it back. There's just not enough demand for this kind of thing.

Plus, this design eliminates the front clip on the pocket that's commonly broken. It is replaced by an M6 screw and fender washer. The cup holder supports itself mainly through the M6 screw. It also supports the entire door pocket. If you have a door pocket with the broken front tab, this cupholder fixes it.
