Mk1 Arc reactor - Iron Man Free 3D print model

Real size glowing arc reactor (you need an led stripe, soldering iron and wire).

Print all the parts outside of the screens folder with black filament or paint it black. The screens with a white filament (use PETG against possible warping due to the LED light) and only 1-2 wall/layers. That way you won't see the LEDs and they won't blind you.
