Y'all might remember Mark Holm posted his program earlier in the week for
mirror cell components.
http://www.atmsite.org/contrib/Holm/cellparts/cellparts.html

 If you are going to silicone these parts to the mirror,
some of you might also like to have the same precision in attaching these items.

 Using Marks Couder file

(This may also work with TEX (Michael Linder/Larry Philips)

enter the diameter of your mirror, and the DIAMETER of your first ring. set
number of zones on mask to "1". check the block to "print
diagonal". hit the "Calculate" tab, Then go into
"ZONES" and edit for your 2nd ring diameter +/-01. PRINT 2
copies.

If you are working with a mirror larger than 8 inches, you'll have to
carefully scotchtape the sections together.

Prick a hole in the center. Place mask on the mirror FACE, and transfer the
center point of the mirror with a sharpie. Protect the face of the mirror
from scratches and turn the mirror over.

The next phase uses the mask and a compass. Remember from geometry that to
mark out a hex, the sides are equal to the radius? Set the compass to span
from the center to the first circle, then step off the hex. repeat for the
next ring. If you are laying out other polygons, here's a page to help.

So now you have a mask, with the points indicated where the support points
should be. Print out another set of whichever components you're using (see
top of page) and tape these to your mask. Now all that's left to do on the
mask is to cut out where the silicone attach points are.
