3D Printed Car Cup Holder Adapter – Nalgene Bottle, Hydro Flask, Heat Resistant PHA Biopolymer, Red Bull Can Slot

This car cup holder adapter is sized for Nalgene 32 oz and Hydro Flask 32 oz water bottles, and can also accommodate standard-size coffee mugs, with a handle pass-through for easy use. It is 3D printed using a biopolymer called PHA which is eco-conscious and renewable and offers excellent heat resistance, making it well-suited for use inside a hot vehicle. This adapter is designed not to warp or melt in your car, and if it ever does, we’ll replace it for free. Many other sellers use PLA or PETG, which are far less heat-resistant and can deform in high temperatures. We chose PHA specifically to avoid that issue.

Two cup holder base sizes are available. Please measure the width of your cup holder to determine the best option:

• Regular: Fits most car cup holders.
• Wide: For cup holders that are 3.5 inches wide at the top or larger.

Colors Available Comes in seven beautiful matte-finish colors:

• Terracotta Red
• Powder Blue
• Lemon Yellow
• Charcoal Black
• Cloud White
• Forest Green
• Slate Gray

As a bonus, every cup holder adapter includes a dedicated Red Bull–sized can holder built into the lower section. It is compatible with both 8 oz and 12 oz Red Bull cans, and should also work with similarly sized cans from other brands.

Free customization available:

These cup holder adapters can be personalized with your name or other custom text. Have a graduation, birthday, or wedding coming up? Add a custom message to make it extra special.
