This is the box belonging to the Puppet (Marionette) from FNAF.

Besides looking cool, it’s also interactive — it includes a crank and a slot to place your phone inside. I’ve included a file you can host on a web server. When your phone is placed in the box and the website is open in the browser, the site reacts to the phone’s rotation. As the phone spins inside the box, it plays the Puppet’s music.
 

For assembly, I connected the Crank and crank connector with glue. I did the same to attach the cog to the phone box. I also added Velcro to the large hole on the box and on the lid so it can be easily removed.

It can be a little tricky to set up everything correctly, so if you have any questions, feel free to contact me!
