Cupholder Adapter for CamelBak Eddy+ 32oz Water Bottle

The 32oz CamelBak Eddy+ insulated water bottle does not fit in some car cup holders, so this adapter sits in the cup holder and fits the water bottle on top. The cup holder part is 71.8mm in diameter at the bottom, sloping up to 83mm at the top (76.5mm tall), so if your cup holder is 83mm wide at the top, it should fit. The bottle itself is 85.5mm, and the opening of the adapter is 87mm (90mm version also available). The height is enough to support the bottle in normal driving conditions, it seems. This has been tested in a Nissan Altima and a Chevy Silverado.

Print with a brim for best stability, but be sure to remove all residual material for best fit. Printing with random seams may also improve fit. Print time for the full-size version at 0.2mm is 10h22m, so test the fit with the short version first, and consider using the 0.3mm (draft) setting for an even faster print (I don't think the fitment would be affected with less detail).

EDIT: Original print's bottle opening shrunk slightly after extended use, so a 90mm version is available as well. Printing in PETG instead of PLA may also help avoid deforming from UV/heat exposure in cars.
