This OpenScad module defines a hollow cylinder with parameters (outside, inside, length) that can be used for filament spooling.
Using a retort stand
It is always better to have the filament roll on top of the extruder. If you got a high ceiling or if you are moving your printer, then you need a portable solution. Together with a "chemistry stand" it will make a fine filament roll holder. Buy a retort stand, i.e. the kind that is used in chemistry labs. Yours could be made of:
A hollow cylinder can be of use with several other filament spoolers.
Printer: Felix 1.0, 2.0 and Pro1
Notes:Any resolution and any infill from 20 to 80 % can do. This one of the rare objects where these parameters don't matter much. Use at least 3 contour walls (I'd say 4 is better).
Configure the OpenScad program and print a hollow cylinder so that the roll can turn with less effort.
Attached pictures show the principle. The STL examples included are for a 12mm bar and either a roll with a 31.6 mm hole or one with a 38.4mm hole. Unfortunately the filament roll holes come in many sizes. Read Richard Horne's attempt to promote an universal size (http://richrap.blogspot.ch/2014/03/universal-3d-printing-filament-spool.html).
Use the customizer to specify your size. Hole diameter is 1.2 for a typical retort stand. Filament roll hole diameters seem to vary from 19 to 74 mm. Frequent ones are 31mm, 39mm and 52mm. Outersize diameter ranges from 12.5cm (e.g. Taulman T-glase) to 30cm. Typical outer width (length of the cylinder to print) is from 6cm to 12.5cm.
This piece can be printed with any 3D printer in any quality. I suggest to use some kind of moderate fill. The printer on the picture is a Felix for which I made the cylinder. Cylinders can be printed in any plastic (except TPE). PLA is probably the best solution since its easy to print, cheap, little friction and fairly smooth surface. I was surprised at how smoothly the filament reels now turn.
Tips for slicing and post-processing
In addition, one also could print 2 short extra-cylinders, insert before and after the big one and then use clamps to hold in position (for long "night printings"), but after a few years I stopped using these. If the horizontal bar is horizontal the reel should not slip sideways.
