This model is NOT expected to hold up to actual use, especially if actual water is added to the bottle. I have not printed it to test it, but I have measured my own 40oz water bottle (91mm diameter) to construct the model. I am not responsible for damage to your Framework hardware or water bottle if it breaks. If you print it, try something more resilient like ABS.
The author remixed this model.
The bare expansion card model provided for modification has had a 40oz LTT water bottle (https://www.lttstore.com/products/insulated-water-bottle?variant=41011168116839) holder added because the community demanded it!
