This is a remix of the Cup Holder Extender With Phone Mount by XKilox95. The only change was to remove the phone holder. Since the model was designed to work with LTT water bottles I also included a model with the LTT logo on the inside. It will print without any supports though I did use a brim just for insurance.
This adapter should fit any 2nd generation Chevrolet Colorado or GMC Canyon.
The author remixed this model.
