Inspired by Jagahati's model here.
I wanted a similar one that would fit a Hydroflask 32oz with a silicone boot. So I remade it and enlarged the opening to 96.5mm wide.
Should fit most cupholders.
(Boot + bottle is 94mm - Normal bottle is ~ 91.5mm)
Highly recommend printing with the following settings:
4+ Perimeters.
50%+ Infill
.28 Layer Height
.5 Line Width
All of these will add to the strength of the print.
