This is a Hand Towel or Dish Rag Holder that can be mounted just about anywhere. I have included the Cubify Invent .FUN files (I used to own a Cube but it expired and was replaced with a Robo 3D.) and the STL files. The inside opening of the towel bar is 7-1/2 inches and the holder holds the towel away from the wall, or cabinet door, for faster air drying.The overall size of the towel bar is approximately 7-3/4 inches x 4 inches x 1/4 inch square. The Holder is approximately 2-3/8 inches x 1-5/32 inches x 1-17/32 inches. The intended hardware is two #8 x 5/8 inch Flat Head wood screws. Double-sided foam tape can also be used if you did not want to use mounting screws. To insert the bar into the holder, slip one pivot end into a hole and compress the bar fair enough together to allow the second end to enter the other hole. Watch for the smile on your spouse's face when there is one less item on the counter.
