Re: Fasteners extending outside the FRAME PERIMETER

(There are even a couple of possible—but unlikely—cases where this isn't the minimum quadrilateral either.)
I was careful (but not particularly clear) to include "right at the corners" in my wording.

What I intended to portray was each corner of the robot having a bolt coming out of each face directly adjacent to the corner, so 2 bolts per corner, 8 total. This should result in the rough approximation you suggested.
