UPDATE 2017-06-19Not recommended approach for a spool holder
This approach is really awkward as you have to faff about with different spindle diameters, etc. etc. I've gone away from this and now use https://www.thingiverse.com/thing:629381. This is a much simpler, easier to use and more reliable spool holder. I strongly recommend it to you too. It's a bit more material and needs four 608 bearings, but trust me when I say that you won't regret it.
Original summary below
My JGAURORA A3 printer came with a nice filament mount that has a 10mm threaded bar to hold the filament spool. Unfortunately, the filaments that I bought have much larger diameter holes through the middle and don't rotate smoothly.
These are trivially simple ends to center the filament spool on the 10mm bar. One has a diameter of ~53mm and the other ~50mm. I need both for the various filaments that I have.
With these in place, the filaments spin smoothly. You need to print two of whatever size you want - one for each end of the spool.
