CO2 Laser Tube 55mm Adjustable Holder

A laser tube holder for a granite laser engraver. At the moment I am assembling a machine and unfortunately I could not find a ready-made holder for a 55 mm tube.
Most likely, I will finish the dampers for the tube so as not to damage it when clamping.
There was also a slight backlash in the lifting mechanism, so I will increase the size of the moving part.
The holder is mounted on profile 2040.
The second gear is not needed for one set of holder. In the next update, I will remove it and also attach each element individually.
