Model Seat belt buckles have a pretty satisfying mechanism, but it’s not a great idea to play with them on the road! Now you can 3D print your own fidget and desk toy to play with anytime that you want. The design features a double action mechanism for locking and unlocking the tongue in place as well as ejecting it. It’s 100% 3D printed with no other hardware required. Featuring 20 30 40 plus different tongue styles, you can rep your ride! Want a different style on your tongue? Edit your own or let me know what you want in the comments.

Due to popular demand I've also created a Wall Mount Key Hanger based on the same mechanism.
