Height of envelope volume to contain 4 side
ribbons. The envelope extends from bottom of
ACDTop volume to back edge of side tiles.
But this isn't quite right! They only go
down to a Z of -15.67 mm, whereas tiles go
down to -45.5. Furthermore, the side parts
of X-ribbons should go higher: nearly up to
underside of the top tiles.
