Edit: Sep-19-2016: changed the design to metric. This is a super duper hanger for the Flashforge Creator Pro and similar printers. This design has a few advantage Bearings based, virtually zero friction. Easy to mount and remove the spool. No screwing required. Easy to install and remove holder from the printer (e.g. in tight places) Fits all common spool form factor and spool holes, including Hatchbox spool with 1" hole. Printing: print in the orientation of the provided STL file. This orientation will provide the max strength. I printed with ABS, 4 bottom/side/top layers, 0.2mm layers with 0.4mm nozzle, 20% infill and support material from the printing bed to that large round bump. Materials: M6*90 screw (e.g. https://www.amazon.com/gp/product/B0143ACXD4), 4 X 626 bearings (I prefer the plastic/glass type, search ebay for '626 Plastic Nylon POM Ball Bearings', they turn smoothly, open don't require lubrication, don't rust, and light weight), and an M6 hex nut. Assembly: debar the spacers and other holes (use a debarring tool such as Shaviv or a large drill bit) insert the bolt into the base, inserts the spacers and bearings insert the end piece and the nut and tighten everything. Verifying your assembly: * Make sure that all the bearings turn freely. The spacers are designed with chamfer at their ends to make sure the touch only the center part of the bearings. * Make sure the end piece is well tighten and that it is pointing up. If it doesn't point up, release it, release, turn the bolt in the base a third of a turn or so and tighten again.
