OpenSCAD Vacuum cleaner adapter (fully customizable)

Some power tools may have special diameter for vacuum cleaner connection instead of standard one.
This is the case with my sanding machine.
So I created a very simple adapter.

Current one is made for connecting Bosch PSS 250AE sanding machine to Kärcher WD6P vacuum cleaner.

**Customization**
All you have to do is specify the diameter of the vacuum cleaner on the one hand, then the diameter of your tool on the other hand.

Of course, you can use this customizable adapter for any household vacuum cleaner, or anything else.

**Attention**
Vacuum cleaner side of connector will be a male connector. You have to specify interior diameter of the vacuum cleaner connection.
Tool side of connector will be a female connector. You have to specify exterior diameter of the tool side connection.

** Hint for a female/female connector **
For vacuum cleaner side, you can fake customizer and integrate the wall thickness with the diameter.

* Example :
Vacuum cleaner diameter is 35mm.
