Customisable Parametric Dyson Vacuum Nozzle Generator

A customisable parametric generator that produces a nozzle that will fit directly onto a Dyson V7 - V12 stick vac. No other adapters required.

The actual Dyson fitting is a constant in the generator. The generator adds a nozzle to the Dyson fitting, allowing you to fit it directly to a Dyson stick vac. The default nozzle diameter is 35mm (same as the Dyson fitting), but this can easily be changed to suit whatever you require.
Many thanks to Ziv Botzer for the original nozzle script.

Elements of the original nozzle script have been changed or constrained to maintain compatibility with dimensions of the Dyson fitting. The following parameters of the nozzle are customisable:
The length of extension from the Dyson fitting to the nozzle joiner
Length of the joiner between nozzle and the extension
Wall thickness of the fitting and nozzle
Total length of nozzle, chamfer and base (excludes Dyson adapter)
Height of nozzle section
Width of nozzle section
Rounding radius of nozzle section
