VESA to SH25 (shaft mount) adapter for electronic microscopes

This is an adapter for mounting two SH25 shaft holders onto a VESA mounting plate.
The SH25 shaft holder is mounted onto the adapter. A 25mm thick precision shaft is inserted between the shaft holders.
A mount for a lens or an electronic microscope, for example, can then be fitted onto this shaft.

The aim is to use a standard monitor arm to mount a microscope.
I’ll add a few photos as soon as I’ve tidied my desk. ;) ;)
