Universal Trash Can

The universal trash can, whether in the office, the workshop, or in the car's cup holder, fits anywhere. Required parts: - A dowel pin, threaded rod, or other rod with a diameter of 2mm and a length of 20-22mm - A torsion spring. I use one with a thickness of 0.6mm, but a smaller one will also suffice.   To assemble, simply place the spring between the retaining tabs in the cover and push the bolt through the retaining tabs and spring. Then click the cover assembly into the housing.
