I tried to contact you offline. I do not know if the message got to you.
I was wondering if it would be possible to get pictures of the 12X12 mirror
retro-reflector that you built. Of particular interest is the method you
used to adjust the relative angles.
My attempts were rather crude and un-successful. That probably was due to
my lack of imagination to "see" the solution. I would like to see how you
approached the problem.
Thank you.

James,
Agree with your inputs. I use the same items.
I recommend the stick on reflective tape. Pretty easy to use and attach.
I've built the 12x12 setup, and it works well, especially when the beam has
expanded to greater than the size of the reflectors, then you get "1" beam
back.
For adjusting, I used a screw/nut arrangement to hold the angles. This
allows easy tweeking of the sides.
