The cap is a fusion of the original cap, visible at https://www.thingiverse.com/thing:4235243, and the iconic biohazard sign from https://www.thingiverse.com/thing:981338. While it shows promise, there's definitely room for enhancement. I've already begun brainstorming ways to improve it by dissecting the STL file in Sketchup Make and making some key deletions.
