Cupholder adapter for water bottles, works great with a Hydroflask or Yeti bottle. Fits 5th gen Subaru Foresters (2019-2023) like a glove.

The included profile is optimized for ASA, took me a couple attempts to get the overhangs to come out looking reasonable. I wasn't that concerned about them and printed it without supports because any overhangs are not going to be visible, but if you want it to look perfect you may want to add some.
