hand key by jorge lopez ortiz from mexico

this project starts with some sketches from a hand, it finished in a hand with a look of a monkey head, the thing is to just push the mouth of the monkey and open the door, if you want to lock it up, you just switch the ear/thumb to do that.
the materials to manufacturing the handle is stainless steel, but you can use other materials like aluminium or brass.
this is a project which main focus is on students and children but anybody can use it
