Gold Kryptonite Storage Warning Sign

The last story of the Silver Age Superman, "Whatever Happened to the Man of Tomorrow?", ended with Superman entering the Chamber housing a sample of Gold Kryptonite and disappearing in the Arctic. Gold K permanently removes a Kryptonian's powers. This is the warning sign that was on the door. I neatened it up a bit from the original.

I have provided a flat version for those with AMS and MMU. I recommend using arachne walls and gyroid infill.
