Lego Head Box

I have been asked by a friend to make a giant lego head box, so this is an empty head with a a cover and snap-in face :
I have scaled it in 2 sizes : 300mm and 40mm
Both versions have there files :
- Base.stl => head without the neck
- Base_with_neck.stl => I let you gess :P
- Cover.stl => Top of the head
- Face.stl => snap-in eyes and mouth
Not printed for the moment, I will update the thing when it will be done.
