The file 'Simple Shelf Support 3D Printer Model' is (stl) file type, size is 39.5KB.
Just like this things name implies, this is a simple shelf support. Weird, I know.
It's quite small right now so you may have to scale it up to get the size you want. I have no idea how strong this thing may be so make sure to test it before you build a shelf and place your precious on it.
Mmmm shelfrilicious.
I added a version with rounded corners.
