Height adjustable drying rack

Simple and extendable drying rack for thin, tall and long containers such as water bottles. I needed 12mm cylinder with 300mm height, designed to connect on the top of each cylinder with threads in various length, allowing you to make 205mm, 250mm, 300mm or 350mm height from the surface of the base.

The base width is 280mm, longer than maximum X-axis length for my Prusa MK3S+ printer, but you can fit it by slicing diagonally without skirt.
