Need an adapter to fit your beloved Nalgene water bottle, Hydro Flask, or coffee mug? Well, you have come to the right place!
This cup holder adapter easily fits in most standard cup holders and is perfect for keeping you hydrated on long road trips, commutes, or even just a quick run to the store. The adapter is designed with the classic 32 oz (1L) Nalgene in mind, but is compatible with most standard water bottles, including those with a diameter of 4 inches or less. Additionally, with the tall side walls and slot cut-out, it’s compatible with the 49oz (1.5L) Nalgene (or similar) as well as the Hydro Flask Mug (12oz) (or similar). The internal diameter of the cup holder adapter measures 3.82? or 9.70 cm.
This is the warm climate version of the Nalgene cup holder adapter printed in resistant PETG filament. PETG filament is resistant up to 185 F, while PLA filament tops out at 122 F.
v2 model alert! As of Fall 2023, there is a new and improved version of this model with supports added to the coffee mug handle slot and overall greater density. These changes are intended to make it even more rugged for your adventures. Cheers!

Wow. Sometimes the simplest things are the best. I can now take my Nalgene with me in the car and not have it falling everywhere. With this adapter, it fits easily in my cup holder. Ordering was simple and service was great. Love it.
