Demon Core
thingiverse
EDIT: Incorrectly sized model was uploaded, should be fixed now. A small replica of the infamous "Demon Core" experiment. Not made to exact proportions, meant to be a "fun" little desk toy. Don't forget your screwdriver! The center cavity is sized to fit a 2" sphere, you can buy a stainless or chrome steel ball bearing which will fit, or print the included sphere. If you plan on painting it, I recommend only giving a light sanding on the outside of the reflectors because the layer lines actually mimic the machining marks on the real one. For a good metal finish, apply Rub 'n Buff silver leaf.
