Seat Belt Buckle Desk Fidget Toy
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.

it says its an unsafe file
What is the purpose of the filament in the bottom? I want to scale up this project and would not be able to use the filament in an increased scale.
What scale do I print this at in cura. I can't get it to work.
How about a Harley Davidson keyring?
I had a look at it, but the details of the logo (words and lines) are too fine for the space available and wouldn't print well. Also, Harley's don't have seat belts ;)
great model and the land rover looks awesome thanks. question and request how do i download just the models i want without downloading all? also my nephews name is bentley could you do that symbol please
Cool name! I've just added it. The file size is getting a bit bloated, but there is no way to download them individually right now.
could you make a dacia one and this thing is very cool
That's a new one for me! I've just added it.
What percentage infill did you use?
15%
Not sure what I did wrong but the case top doesn't snap fit for me. It should be much larger.
Check out Francis_Mk3S' revision of the top part in geometrically related models above. That may help?
Great model! I have switched to using this as my test print for new filaments. I can get away with printing all parts in one batch. Granted I have to do more post processing and I have a solid colour buckle, but still, a 3 hour print for something that can be fidgeted, top job.
Thanks. That's a great idea!
