Spools rack (16mm) pole holder

Filament spool rack / shelf.I used a 16mm diameter and 1.5 meter long chrome metal pipe from a local hardware store. I admit that a copper pipe with holders of the relevant color would look quite stylish. I would recommend using the middle holder for every 0.5-0.7 meters. In my case, there is one middle holder for 1.5 meters (for 0.75m), it holds 10-12 kilograms without visible problems.The next idea, if you put spool width tubes on bearings between the two holders, it can be used as an additional spool holder for the printer.
