Hammer Lock / Keyhole Bunnings Shelving Hooks (FreeCAD)

Remake of my OpenSCAD model.

Drawn in FreeCAD with source file available.

STL supplied is compatible with these Australian Bunnings shelves by Montgomery. It should be a snug fit without any noticeable play. Adjust the FreeCAD file to your shelf size.

I printed in PLA with 50% infill and it is strong enough to hold anything I would want to hang on such shelves.

Update: I've added a “straight” hook STL and FreeCAD files, which contains a locking tab so the hook can not accidentally be slid out when removing items from the hook.
