Holo Projector With Hole

This is the Holo Projector for this R2 ...............

it was suggested to drill it out to 5mm to add LED's for effect but I thought it's easier to print it with a ready made hole! I also widened the top of the hood slightly since it didn't print too well on my printrbot simple metal ........... hole size is actually 5.7mm but a 5mm LED fits snug probably because my wall thickness is set to 1.2 on my printer
