Customisable Parametric Dyson Vacuum Adapter Generator

A customisable parametric generator that produces an adaptor for a Dyson stick vac (V7 - V12) to allow fitting a standard vacuum slip-on friction fit nozzle.

The actual Dyson fitting is a constant in the generator. The generator adds a cylindrical adapter to the fitting, allowing you to fit any standard slip-on friction fit nozzle. The default adapter diameter is 35mm (same as the Dyson fitting), but this can easily be changed to suit whatever fitting you require.

The following parameters of the adapter are customisable:
Set the length of the intermediate joiner between the Dyson fitting and the adapter, allowing for a diameter difference between the two
Set the diameter of the adapter
Set he length of the adapter
Set the amount of slight reduction at the end of the adapter nozzle to help with a good friction fit
