Stand alone 5 times Filament Rack

Inspired from "Auto-Rewind Spool Holder for RepRack" at https://www.printables.com/model/292276-auto-rewind-spool-holder-for-reprack/comments by "Jerrari", I create some parts to assign the spool holder in a stand alone rack. In the center you will need the modified cross in the spool holder. I replace the rollers with a pure roll and I think its recommned to coat it with a rubber coating spray. Download the filament roller at the given source. You need a threated rod M8 x 525mm (with 6 nuts with 6 washers) and 2 pipes with a outer diameter of 21,3mm (1/2") x 500mm.
