This is an adapter that will let you fit bigger water bottles like YETI into kids car seats! Kids car seat holders are smaller than standard cup holders so a lot of bigger bottles won't fit. This was specifically designed for the 12-oz YETI Rambler Jr. Bottle (see pictures to see the holder in action!), but will also fit the 18oz adult rambler and many other standard sizes of water bottle. Also works great for some small cupholders in cars/trucks that can't handle the bigger bottles too!
This is 3D printed using PETG, a tough thermoplastic with high heat and UV resistance. It's the same kind of plastic used in many bottles, is food safe, and will hold up in the car.
Pairs perfectly with our Kids Snack Tray! https://printerlife.etsy.com/listing/1672576956/kids-carseat-cupholder-snack-tray-for
Tested with a variety of car seats and car/truck cupholders. I personally have 3 different styles of Graco carseats and it's worked for many other seats like the nunea ace, nuna rava, etc. Offered in a variety of colors, pick something that matches your car or your kid's personality!
71mm outer diameter for the bottom - this is the smallest carseat hole it'll fit into. 79mm inner diameter for the top - this is the biggest bottle it can fit.
