Nice idea. Is it just the friction caused by tightening the nuts that keeps it at the angle you want? I can see this as a good travel option to take into a library, since the right sized version could fit in a backpack or briefcase and work for a variety of book sizes. With hardcover books you wouldn't even need any acrylic to go across the beams, just some for a platen or something to take it's place. Perhaps also it could use something adjustable to support the spine to keep it up from the vertex. That would act like sliding the adjustable cradle apart for a wider book. Any ideas on a packable platen that would be easy to pick up to change pages?

Also can you specify the materials you used and what to look for? That's a pretty good price.

I like it!
Instead of relying on tight nuts to keep your angle, you could have 1 more of those aluminum strips bridge the hypotenuse between the top threaded rods from left to right. Set the angle by choosing the distance between the holes drilled. Maybe drill several holes in that strip so you can adjust the angle (if desired). This would let you set up on a flash, no tweaking. Use a wing nut on one side (or no nut might be ok too) so you can easily disconnect the restraining strip for take-down.

Maybe even a string or small chain would do the job, but a matching piece of flat metal seems like the best fit for this particular project.

I would also consider rounding off or cutting off the bottom corners to prevent scratching the table that your cradle is on. More foot surface area would help it stay in place too.

Add a strip to quickly set up cradle to same angle.

This design could fold flatter for storage and transport if you offset the holes for the threaded rods at the top and drill out the contact areas. All the left pieces are the same, and all the right side pieces are the same.

I might say to clamp all strips to drill the bottom holes, then drill the top 2 holes through all pieces.
Then unclamp, select just the left side pieces to drill out the contact areas just from the left sides.
Unclamp, select the ride side pieces, and drill out the contact areas of just the right side pieces.

Grey circles are the threaded rod.
