"""Kingbright surface-mount chip LEDs: a laminate substrate with a terminal at each end and a clear moulded lens on top. Top-view
packages APHHS1005 (EIA 0402), APT1608 (0603), APT2012 (0805) and APT3216 (1206), and the side-view APA1606, which lies with its lens
facing +Y. The part is centred on the origin, its length along X, standing on the board (the XY plane) on its terminals. The substrate,
the lens and each terminal are their own solids. Dimensions from Kingbright's data sheets; see the README."""
