The rear seat cup holders in a Hyundai Ioniq 6 are pretty small and don't fit most bottles. These adapters will allow you to store a 3.5" water bottle. The armrest will not fully close with the cupholder in place.
Please verify the diameter of your water bottle before ordering. The sides extend 1.25" inches beyond the bottom of the water bottle so even in hard braking situations, your top heavy bottle won't go flying.
These are 3D printed in PETG so they are UV and heat resistant to nearly 170°F (75°C)
