Microscope Stand

I really liked [Perinski's Microscope Stand](https://www.thingiverse.com/thing:3379567), but I wanted a stand that use a door blocker as base, uses 8mm aluminium rod, and with a more rigid bracket for axles assembly.

I completly redraw from scratch the Perinski's design to fit my needs (except for the microscope bracket hook: I just add some screw holes to it).

STEP files are included.
