As it's merch Monday, just sharing my latest commission that shipped out to a hopefully happy customer today.
Model was sculpted by me years ago in TinkerCAD, long before I learned how to use zBrush, Blender & Fusion360. I sculpted it solely using the reference image from the game (last pic) when Link collects the key & used a little creative interpretation to figure out the shapes of the sides you can't see.
To this day, it's one of my favorite props I've designed.
