If you own a LandRover Defender and a 3D printer then this might be of interest. This cup holder fits into one of the spare switch slots on the centre console.The holder needs a firm push to click into place, but once it is in, it is very stable and secure. The holder is off-set to the right, in order to avoid hitting it when slecting fifth gear. If you drive a left-hand-drive Defender, you may need to mirror the part so the off-set is the other way (or you could just turn it up-side down, but I haven't tried this). With an 80mm diameter ring, it fits most takeaway coffee cups.....
