This is a fun little project for anyone who keeps losing their keys. It’s designed to look like a tiny street trash can, but with a hidden surprise tucked away inside. When you hang your keys on the hook at the bottom, the weight activates a simple internal mechanism that makes a small panda peek out from under the lid. It’s a clever mechanical design that adds a bit of personality to your entryway or office. The gray, industrial look of the bin contrasts nicely with the cute animal inside, making the mundane task of hanging up your keys a lot more entertaining.

I test all my models with default Bambu Lab slicer settings: 0.2mm layer height, 10% infill, tree supports. No complex tweaks needed. If a model requires special settings, I include a prepared 3MF file (rare).
