100x160mm sign, with atom art. 

The recipe for the cocktail version of the atomic discombobulator involves lab ethanol and a spritz of superheavy water. Given that tritium and derivatives are expensive and often subject to radioactive licensing requirements, it is acceptable to make a diet version by substituting water saturated with caffeine. It tastes like something you will wish you had not tasted; but that's OK: you won't remember.

Mesh and Solid models provided. The solid version might be an easier print. 
Best with color switch above 1mm, as with included gcode for the mesh version.

Also see the Shadowbox Frames, into which this and the rest of my sign collection fit.
