Star Discovery Mount Spanners

The "Star Discovery" mount for telescopes has 2x internal plates to adjust the mounting bearing (Span29) and motor drive clutch (Span22). This is a spanner to suit to aid in adjustment (space is too narrow to fit an off-the-shelf adjustable spanner.)
I have only tested the "Span29v2", but this was borderline not stiff enough, hence I've made "Span29v3" deeper on the sides to increase stiffness; try this one first.
I found I had to rotate the entire mount with the spanner such that the friction of the bearing helped to loosen the cover plate.
