This is a small parts bin I made to help keep organized. It is made out of scrap cardboard that would otherwise be thrown away. Similar parts bins may be found in stores for approximately two or three dollars each.This pattern was cut out of the cardboard using a homemade CNC machine, but I have also made them by hand with a box knife. Once the shape is cut out of the cardboard, fold on the dotted lines, and glue as shown in the picture.
