I designed and printed bearing rollers that supported the outside rim of a filament spool but discovered that it still caused a fair bit of friction. This roller sits inside the spool and bolts through my printer cabinet. Super low friction. Built around 608ZZ bearings but I've included the Solidworks files if you want to adapt it. No supports needed (I added wee 45 degree slopes so make sure you print it the right way up). I print the spacer separately using Spiralize or Vase settings, 0.8 line width. You'll need M8 threaded rod, washers and nuts. I guess you could print those too.
