Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5355810.
I kayak regularly and placing a water bottle horizontal inside rolls around as the kayak moves, and it mildly annoys me, It is also useful to keep it from rolling around when placed on moving surfaces.
Might work for other brands, just resize the model to your water bottle diameter. Currently the diameter is at 92mm, use this number to shrink and enlarge by ratio to your desired diameter.
Printed in silver PLA and later in blue TPU as in photos.
