I've been seaching for these with little luck. There's videos and some threads but all of the ones I've found aren't throughout enough to actually follow from start to finish.
I started making one, but gave up on it at this point. I need to rethink the plans.
In the mean time, the simplest thing that I have seen is two pieces of glass and some binder clips. Sandwich the negative and paper between the glass, and use a couple of these:

Mine is A3 in size. I made it from Aluminium profiles for window frames linked in corners by their special corner pieces. It is quite solide. i've used some thicker glass for it and a hard plywood sheet on which I glued a sheet of cork. i wanted to use it as a paper press, too, and therefore the pressure is obtained by some large screws and it is even and substantial. I had to make some inner pieces (wood) introduced and glued into the Al profiles of the frame in order to support the female screws on the correct position.
I use it for my alternative processes and the higher pressure makes a big difference in sharpness compared to my older, classical frame.
I found a 'stereo' cabinet at the curb a couple years back and took one of the shelves.
All I ever used is a piece of glass. I have two "contact printers" but I don't trust the cleanliness of the foam rubber.
Dan, your solution is really brilliant. There's a US company called 80/20 Inc. that makes aluminum extrusions that could be used to make something like this. They called in "Industrial Erector Set" (Erector set was a toy building kit I had when I was a kid, I don't know if they still exist.) Their catalog is available here: https://8020.net/bookshelf
