My wife got this gigantic Stanley Mug that would not fit in her cup holder and requested a print to “make it work”. It fits in a 2018 Q7 and is able to hold the 40oz mug upright wile driving. I printed it out of PETG at 0.2 using the prusament PETG profile. May work for your car, but would recommend measuring first.
The base is 70mm wide by 66mm tall.
