The file 'Universal Spool Holder 3D Printer Model' is (stl,zip) file type, size is 4.7MB.
This is a "universal" spool holder for those that use an 8mm rod to mount their filament spools (ex. RigidBot). It is essentially the same as steveho's design, so all the credit goes there. This version has looser tolerances and the threads print cleanly and fit wonderfully. I had some issues that needed serious post processing with steveho's version.
There's something about 3D printed parts that fit together...
Update: Added untested models (zipped) for Flashforge / Powerspec (Creator Pro Style)
Update December 2, 2018: Added a larger diameter cone (cone_90mm) for spools with larger holes.
