Kevin would be the best to contact for production quality but I can get you something that will work fine. Do you want a drawing file or an image file?
The Tosten website has a "user manual" or "installation" PDF that has a line drawing of the grip on it. I planned to bring that into an application like Adobe Illustrator ($$$) or Inkscape (free - www.inkscape.org) and delete everything but the grip drawing, then use the same program to label it as needed. I just haven't done it yet, despite having installed the Tostens a couple of years ago...
Here is an Autocad file that I put together based on what pazmanyflyer sent me, and more from the Tosten site. I added my labels, but that is an easy edit in Autocad.
Thanks for help and pictures. Here is something I made from these resources to try and be compact yet document the stick functions. I am planning to put this on my panel as a reference.
