Support bracket for finder scope

The mounting bracket for the finder scope of my 8 inch (cheap Chinese) Newtonian telescope was simply far too small, and has never been really stable. This bracket significantly increases the footprint, and makes the finder scope mounting entirely stable. This requires that this plastic bracket is properly glued to the telescope tube, since the mounting screws alone does not bring sufficient stability (especially so since they are only secured in the thin tin telescope wall).

The bracket can readily be adopted for other dimensions via the Openscad design.
