The file 'Lovecraft Cthulhu Tentacle Shelf Bracket 3D Printer Model' is (stl) file type, size is 50.2KB.
UPDATE: I've changed the thing to WIP because want to make a version with slots for wooden inserts, allowing you to mount them with a screw through the wood, rather than plastic which tends to split when screwed to the wall.
I designed these for heavy lumber shelves. You can just screw the brackets to the wall a place the shelf on top, but I designed them to embedded in the wood by chiseling out the negative. The shelf can then be secured from the bottom.
