Dodecahedron 2 inch edge

I need to make a dodecahedron with two inch edges for my geometry course. This is what i came up with! The angles are 116.56 degrees. As I'm sure you know this requires the printing of 12 faces then 30 angles. I wanted to be able to open it, so i made the "Lock" so i could pop it in and out. (Yes I put a LED in it!)
