I hope you are all subscribed to Michael42ers YouTube channel. It is a regular source of amazing paper creations and modifications. He's excelled himself once more with this delightful Mexican Peck in a Paper safe. Fantastic!
Whilst on the subject of modifications I have to draw attention to this beautifully crafted Gear Train which maxlrainer posted in the comments section. Thanks for sharing Max! I've made the changes to the file that you suggested.
