need some help please!!!

hello everybody,

i´ve got some bad problem with my grasshopper-file.

i want to build some kind of lamp out of triangular shapes and i made this script for this project. the material i want to build this lamp of, shall be paper.

so, my problem is that the surfaces of this triangular shapes are cutting each other and if i want to build this out of paper it wont work, because the surface i want to use is curved.
 i know that i could use another surface, some kind of rectangular, but i want to have this one, which is in the rhino file that i have uploaded!!

is there anybody, who can help my with thhis issue?! please.....
