A little model for a project of lamp i'm working on. I've remixed the work of Igotron with a more compact layout and I've hollowed the crystal so you can put a light source in the middle.

I printed my versions using transparent ABS at 200nm layer height. The left one has been polished with acetone but I find the non polidhed version more appealing. The crystals' angles make any support removal verry easy, so don't be afraid to put some support in the middle of the print if need be.
