This parametric model can be adapted to fit any cupholder/cup combination while remaining support free. I have provided a selection of popular sizes as STL files and print profiles. If a custom size is needed you can either comment the cupholder and cup dimensions and I will upload the resulting model, or you can input your dimensions directly to the Fusion 360 file parameters by following the guide below.

The bottom of the adapter is left hollow, so that it can double as a convenient car-trashcan if desired.

I strongly recommend ABS or ASA if this will be left in the car long-term.

Medium cupholder size based on 2012 Toyota Camry, as it is possibly the most average car.
