12 sided calander

This is gonna be somewhat fun to making 12 sided calander paper ball.
You can even choose from a few languages. There are two types: Calendar on a regular dodecahedron which needs glue to stick the sides and Calendar on a rhombic dodecahedron doesn't need glue at all. I think I prefer the one without the need of glue.
