My cup holder adapter is designed to fit Stanley's, Yeti's, Hydrofask's and other comically large water bottles in your puny cup holders. There are various base sizes from 85mm to 65mm in diameter to fit inside various cup holders.
The TPU restraining tabs are optional but are required for any bottle too small to fit the 100mm inner diameter of the adapter. I recommend you add a dab of super glue to hold them in place.
If none of the available sizes fit your particular cup holder, post the diameter and depth of your vehicles cupholder and I will try to upload a variation that fits.
If your vehicle gets too hot, consider printing it in more temperature resistant material like PETG
