The cup holders in the 2024 Corolla Cross do not fit the wide-bottom (91mm) Hydro Flask. This is an adapter that fits in the cup holder. Note that some models of Corolla Cross (2022, for example) have a different style of cup holder. Please check this will fit before you print. The STEP file is also available if you want to put your own spin on the design.
I used PETG for the heat tolerance at 0.2 resolution, no supports!
