Rotatable Slideholder for Leitz Microscopes

This is a rotatable slide holder for microscopes. It was designed for a Leitz Otholux II. I add the scad files, so that you can adopt the holder to any other microscope brand.
The rotatable inset holds the slide or a usual 7 cm Petri-dish (either base or cap). The slide is placed on the object table, so there is no problem with focusing the condensor. The design is very flat - there is no risk for the objectives...
