Spray Can Cap

This. Everything humanity has been striving towards over the last 10,000 years reaches its climax in this, the most essential object in existence. Every breakthrough in thermoplastics, every moment spent by the original RepRap team, every snooze taken by Edison, every equation drawn by Newton, Euclid's scribbles on the ground at Alexandria, agriculture, and the first stone tool noticed by a resourceful ape - each of these is a vital link in the unbroken chain of progress that leads to this model. Alongside Archimedes, Turing, Salk, Berners-Lee, Stepanov, Von Liebig, and countless others who laid the groundwork for creating this spray can masterpiece, we must also acknowledge Kelly Egan's role in crafting the original prototype. I have refined Egan's work and thereby secured my place in history by expanding and directing the spray chamber. Until 3D printers achieve sub-micron resolution, we will need to activate the spray by pushing a hot needle through the nozzle. The optimization of aerosolization is left as an exercise for the reader.
