[cctalk] Dec rl02 disk pack shelf design

Hello, I have many rl02 disk packs for my pdp 11/34 and 11/05. I have just been stacking them upright, but that has not been the safest or the most space efficient. Were any kinds of shelves made for these disk packs, perhaps similar to 9 track hanging tape racks? Trying to make things look more organized too. Hoping someone here has one and can share a pic, perhaps it is a design i can duplicate and make with some woodworking tools. Thanks, Devin D.
