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.

The model works pretty well. Only thing is that the filament at the bottom didn't do much, and the top cover didn't friction fit-on the base. Other than that, I'm impressed.
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?
