Parametric column extension for digital microscope

I bought a small digital microscope to do electronics, and as is often the case with most of these cheap devices, the working height is sometimes too limited to allow soldering under the microscope.

So I have modeled a parametric column extension to be able to raise the microscope.
It is possible to play on the following parameters in Fusion 360 :
* column_height
* column_diameter
* sleeve_height
* sleeve_thickness
* spacing_gap (for sleeve)

I hope it will help other users.
