Gas cap tethers are very important to make sure the lid doesn’t get lost and expose your car’s inner workings from being exposed to water, debris, or the risk of fuel leakage that could lead to long-term damage.

There are plenty of reasons why keeping your gas cap secure is important, which is why this replacement gas cap tether model is perfect for keeping it where it needs to be.

Air Freshener

Sometimes the aircon your car vents provide simply doesn’t do the trick, and once the new car smell inevitably fades you’re going to want to replace it with something different. This interior car fan made as both aircon booster and air freshener to keep your car smelling great!

3D printed car accessory air freshener

This simple but unique 3D printed car air freshener is designed to be swabbed with your preferred scented oil and attached directly to your car’s aircon unit. Once the air is flowing, the fan will help disperse the pleasing smell throughout your car and make drive time more relaxing for you.

Personally, I prefer vanilla, but of course, you can always choose your own favorite. The best part is, when you want to change scents all you need to do is wash the fan off and re-dab it with whichever oil you like! The model’s curved shape even makes it completely safe for use while driving, so you won’t hurt yourself on the ‘blades’.
