My 2023 Chevy silverado cup holders were too small for a 40 oz hydroflask. I don't like the cup holder adapters, so I made this model to hook to the door or center console pocket. This model could be hooked to a shopping cart, or anywhere a 10mm lip is. I printed in PLA with 30% infil and has held in my truck for a couple months just fine (no issues with a full water bottle). I intend to reprint in ASA when it fails. I used tree support to print the “hook”.
