Description

🔒 Seatbelt Lock – Keep Kids Safely Buckled In
This seatbelt lock is designed to prevent children from accidentally unfastening their seatbelt, providing an extra layer of safety during your car rides.

I’ve made multiple revisions and thoroughly tested it in real-life situations to ensure it’s both durable and reliable.

✅ How to use:
Print the lock

Slide it over the buckle

Insert the belt tongue through the opening — that’s it!

To release the seatbelt, simply use the included tool, your car keys, or house keys.

🖨 Printing recommendations:
Material: PETG, ABS, or ASA (PLA is not recommended due to heat sensitivity in cars)

No supports needed
