Hanging box system

The hanging box system can be easily moved to where it is needed.The box holder is attached to the table top from the back with a "pin" or screw. Then it is possible to hang the boxes on this holder, to exchange them with each other. For strength, I printed the holder as in the picture and used a simple support on one side. I printed it in the same way with the screw-on version and used the layer max. 0.16mm. The screw-on version is for a tabletop thickness of 12.5-20mm. Boxes can be printed completely without supports. The screw is also without supports with a layer of max. 0.16 mm. The tolerance for the thread is 0.2 mm, it is just right for me. But you have to test on other printers The pins need to be tested for different thicknesses of the table top, but it is not a problem to increase or decrease the pin in the slicer in one direction.I will add the dimensions and shapes of the boxes
