Halo CE Beam Emitter

This is the iconic beam emitter structure from the first level you set foot on the holy ring. The geometry was extracted from the game and heavily modified to be 3d printable. There are a few built in supports that are designed for a 0.2 layer height. But the large overhangs will require additional generated supports. 

If you want to print this larger I'd recommend the no supports version and set up your own.
