Key holder with built in shelf.

thingiverse

We wanted to keep all our keys organized at home, so I designed a shelf with key hooks to store them in one place. This print has three simple parts: "door1," "door2," and the main body, "keyshelf." Please excuse the rough design, as this is my first attempt at printing it at 0.3 layer thickness. Fortunately, it worked without any issues, and I didn't need to use support material due to its thickness. The holes are 3mm in diameter to screw into the wall securely. Recently, I filleted the pegs to make them stronger, and you can find the updated STL file attached. This design is compact, measuring 155mm wide by 110mm high by 62mm deep. On top of it, there's a bevelled shelf for added convenience.
