Microscope Stand (Bigger)

This is a remix of https://www.thingiverse.com/thing:2525155
I actually redesigned everything on fusion 360 to have:

- longer horizontal reach (added 15mm)

- taller reach (added 45mm)

- bigger and flat base. Since the baricentrum is more on the front side the back support can be avoided, I provided both base version

- smaller knurled knobs

- support for the pinion/knob printed separately to avoid cracks, supports and add more strenght due to filament orientation

- holes diameter adjusted to 3.4mm/3mm on mating holes to avoid the use of nuts (screw directly in the holes)

Support is needed in the pinion and in the screw counterink of the slider
