Backseat Organizer Customizable Drink Holder

Meet the SlideLock Backseat Organizer, a practical 3D printable holder for drinks and small everyday items, designed for passengers in the rear seat.

The organizer mounts behind the front seat using the headrest posts and is designed to keep drinks, snacks, phones, wipes, small toys or travel essentials within easy reach. It is especially useful for stops at road trips, daily rides, or anyone who wants a cleaner and more organized car interior. Use it only during driving breaks.

The model uses a simple two-part slide-lock system:

1. Hanger piece – slides over the headrest posts
2. Organizer bin – slides onto the hanger piece and locks into place

This makes the model easy to mount, remove and print. No permanent modification to the car is required.

The front of the organizer is also customizable, so you can add a name, short word, symbol or small personal detail. This makes it great for personalized car accessories.
