SummaryI recently purchased a Flashforge Creator Pro. The spool holders that came with it have a large diameter that didn't fit any of the spools of filament I already had from a previous printer. So I sketched up this spool holder and it does the trick. I will be making a new file that is a bit shorter when I get a chance. I used ABS at 230 degrees with full support.InstructionsI made it using SketchUp.
