"I love you" keychain with Moving Parts

I all,

This is my "I love you" keychain with with Moving Parts.
The keychain size is 3.7 cmX 7cm a good size for a keychain.

As a lesson from "heytiger" print result I revised the model and made the pins robust .I also changed the gears and increased the thickness of the bottom of the keychain .
Now it should work as expected. waiting to see your results

Print keychain v3 and gears .snap the gears into place.

enjoy...
