Universal filament stand with bearings

thingiverse

This is a universal filament stand for standard spools (160 mm), but it also works with bigger spools up to 110 mm width. Just get two of the prints (they are symmetrical) and you're ready, then all you need are four bearings type 6202RS (35 mm x 11mm with a 12 mm bore). You can easily find these bearings on Ebay or Amazon. To assemble the rods and bearings, stick the rods in the freezer for about an hour. Then heat up the bearings for ten minutes in the oven at one hundred degrees Celsius (they are specified for a working temperature of one twenty degrees Celsius). The rods will shrink slightly from the cold, and the bores of the bearings will get a bit wider because of the heat. That's when you can simply plug them together. Once both are back to room temperature, they will be firmly connected. Then press the bearings into the printed parts, and you're done.
