Mounting screw threads for VR201?

[Ethan Dicks]

Hi, All,

I don't happen to have a VR201 here right now to measure directly (or
I would just do that), but IIRC, there's a threaded mounting insert on
the bottom (for the "E.T. Stand", if nothing else),  I want to
fabricate a shelf clip for a VR201 and am seeking the diameter/thread
pitch for the insert.  Does anyone have that info handy?  It's likely
larger than 1/4-20 from what I remember.
