Lovecraft Cthulhu Tentacle Shelf Bracket

thingiverse

UPDATE: I've modified the design to WIP status because I want to create a version that accommodates wooden inserts, enabling users to securely fasten them with a screw through the wood instead of plastic, which tends to crack when screwed into the wall. I specifically engineered these brackets for heavy-duty lumber shelves. You can simply attach the brackets to the wall and place the shelf on top, but I designed them to be embedded in the wood by carefully chiseling out the recessed area. The shelf is then securely fastened from underneath.
