Bought a cheap digital microscope with a steel plate as the work area for SMD soldering.
Had a small portable screen with 75mm Vesa mount I was using for work and wanted to mount it on the microscope.

f3d file has some parameters you can play with if you want to adapt this mount to a different lens size or a 100mm Vesa.

In the pictures you can see I didn't print the top (2 vesa screws) as I ran out of filament, still works with my screen.
