When I needed a new bin for my classroom I decided to make it myself. Since we just had bought a new vacuum cleaner for another art classroom I had a very big cardboard box with a nice picture of the vac on it. I used this to make a new round bin. As a model I cut apart a paper coffeecup and re-sized it after some measuring on the cardboard. I taped all the seems with red and white tape and drew the vac pictures into robots with a black marker. There is actually not much to it so I made a quick drawing how to do it.
