Holo Projector With Hole

thingiverse

This is the Holo Projector for this R2 unit, and I'm impressed by its sleek design. Check out the 3D printing files at https://www.thingiverse.com/thing:2290050 to see how it's done. Some users suggested drilling out the hole to 5mm to add some LED lights for a more dramatic effect, but I opted for a simpler approach - I just printed it with a pre-made hole! I also tweaked the top of the hood slightly since it had trouble printing on my Printrbot Simple Metal printer, especially when the hole size is actually 5.7mm. Fortunately, a 5mm LED fits snugly in place thanks to my wall thickness setting at 1.2mm on my printer.
