Universal filament stand with bearings

This is a universal filament stand for standard spools (160 mm), but it also works with bigger spools up to 220 mm width. You just need two of the prints (they are symmetrical), 4 bearings type 6202RS (35 mm x 11mm with a 12 mm bore) and two aluminium rods with 12 mm diameter and 140 mm length.

You can find the bearings easily on Ebay, Amazon etc. In order to assemble the rods and the bearings, put the rods into the freezer for about 1 hour. Then heat up the bearings for about 10 minutes in
