Spray Can Cap

This. Everything humanity has been striving towards over the last 10,000 years reaches its culmination in this, the most useful object ever created. Every advancement in thermoplastics, every moment spent by the original RepRap team working tirelessly day and night, every rejuvenating catnap Edison took, each ellipse Newton drew, Euclid's scratch marks in the dust at Alexandria, agriculture, the first flint noticed by a clever ape - all of these are links in an unbroken chain of progress leading to this model. Alongside Archimedes, Turing, Salk, Berners-Lee, Stepanov, Von Liebig, and countless others who laid the groundwork for this spray can's existence, we must also credit Kelly Egan for creating the original design. I have modified Egan's masterpiece, securing my place in history by expanding and directing the spray chamber. Until 3D printers achieve sub-micron resolution, we must manually enable the spray by pushing a hot needle through the nozzle. Maximizing aerosolization is left as an exercise for the reader.
