About this 3D model

This is the brilliant board game connect 4, but now you can wear it everywere you go! Its a Keyring Connect 4. Just need to print the 3 files (The 3rd file twice) and you can start playing. It has a secure system so the circles doesn´t fall to the ground. Maybe it is a little bit big to join it to your key house ring, but it is very suitable for a backpack.
