Control knob for injection mould tool

Hi I would like to get the following control knob designed for multiple manufacturing files such as STL, Step and others for use with Autocad, Autodesk or solid works.

It was originally done as a mesh file OBJ and converted to solid works file however we are under tight time constraints (I need this done by Monday) to get different dimensions of the control knob.

24mm as per file
19mm
15mm
12mm

For the outer diameter.

The internal shaft hole will be the same across all products.

I can't attach the file to here so could you please provide your e-mail address so I can send you a drop box file?

Thanks

Luke
