So I’ve attached cut files for these shelves:
minus the Sisyphus icon by Nikolay Necheuhin of the noun project. They are sized for proofgrade medium draft board or plywood, proofgrade thick draft board or plywood, 3mm and 1/4" (6.35mm). I have only cut these in medium proofgrade, but I believe they should work in the other sizes. I use 3.3mm for proofgrade medium and 5.4mm for proofgrade thick. It will take about one and a third sheets of draft board/plywood so three sheets would net you two shelves. The fit with only the shelves, and not the backs is loose and wiggly. Once the backs are inserted it is pretty solid.
The shelves were a generic request to the forum from she_is_evil. I made them mainly because it forced me to do a couple things I wanted to explore in OpenSCAD. They definitely furthered my ability to think in how to structure physical objects with repeating patterns.
Here is a shot of how the backs (except the very first one at the bottom) have a tab that slides into a slot in the shelf. To assemble, insert shelves first and then insert the backs.
The two dozen clamping jigs on the bottom shelf are not included; they photo bombed me.
The inside width of the shelves depends on the file, but ranges from 9.8 - 10 inches. The depth of the shelves from bottom to top are 3.5, 2.5 & 1.5 inches. In the file, the side pieces are rotated such that any artwork placed on them will be facing out (or in if you assemble them backwards.) The files below were saved from Inkscape as plain svg. The one in the pictures above was cut from an Inkscape svg. I’ve heard people who use Illustrator have trouble with the latter format, so I posted ones saved in the former. If they don’t work out you can let me know and I’ll post the ones saved as Inkscape svgs.
