    Hi,

    I built this paper lamp and am trying to figure out what shape it would be classified as (dodecahedron, etc.). I've attached a picture of the shape, thanks for your help.

    Making this requires insane 3d visualization. How did you do it?

    I just figured it out as I went, orginaly I wanted to make a dodecahedron but it wasn't going to be big enough for what I wanted [putting an LED light inside of it et cetera..]. Each pentagonal pyramid is 6 sheets of paper that I folded into sort of interlocking triangles.

    Are the edges where the faces are glued together part of the figure?

    If not then the platonic solid consisting of 12 faces, each a pentagon, is, in fact, a dodecahedron.
