Stacking spool rack for filaments

This modular stacking system is suitable for spools with filaments of 160mm diameters and more. The pipes between the stands have a diameter of 22 mm. It s cut broom handles that can be bought in supermarkets. The pipes are made of metal and covered with a plastic coating. This surface ensures a solid connection between the pipe and the stand. One pipe with a length of approx. 130 cm can be bought for approx. 1,2 EUR.Other pipe may be loose in the hole and the structure will not be solid. For a smaller tube (e.g. 20mm) it is possible to create and print a sleeve into the hole. For greater strength of the whole structure, the parts can also be glued together with a suitable glue.For a larger distance between the uprights than 1.2 m or pipes made of plastic or other fragile material, I recommend putting a next support upright in the middle. If there is such a request, I can quickly model it into an stl file. Likewise, if there is a request for a different pipe diameter or smaller lower l
