I plan to have some 24 images printed in 90x120 cm size (35x47 inches) and then mounted on Dibond, backed with an aluminum frame for keeping them plane. They will weigh about 5 kg the piece (11 US pounds). I will have them wrapped each in its own folder (s.k. "Rahmenkarton", frame cardboard.)
My idea so far has been to have my carpenter custom make some shelf modules 15 cm high (6 inches) and store 3 images per shelf. Ideally, it should be 1 image per shelf, because I will need to move 1-2 to get out the lower one(s).
Anybody got a better idea? I have not been able to find a ready-made solution. (Based in NE Germany.)
