"""Keystone colour-keyed through-hole test point: a wire-form loop on a nylon base, miniature (5000 to 5004, 5115 to 5119), compact
(5005 to 5009, 5120 to 5124) or multipurpose (5010 to 5014, 5125 to 5129). The base stands on the board (the XY plane) centred on the
origin; the loop is in the XZ plane above it, and the terminal's legs run down through the board. The terminal is one solid, the base
another. Dimensions from Keystone's catalogue page; see the README."""
