Field notes
The page presents a detailed control-drawing-style specification rather than only product photography or marketing copy. It contrasts a vented screw-top version with a sealed version, and gives concrete manufacturing dimensions including a 1.25 mm wall, 0.5 mm internal radii, and 1.5° draft angle. The first run is described as a tooling-funded pre-order, so availability remains tied to production.
