Quarter Turn 5 Dollar Filament Spool Holder

Quarter turn Spool Holder for ProtoParadigm's five dollar filament

UPDATE
I just added a new version of the male flange called "undersized". Some people have no issues but some say the detents are too tight. The undersized flange detents are .02"(.5mm) smaller then the original, so If you print the original and have issues with the detents breaking off then print the undersized male flange instead. Let me know which one works best?
Or try the threaded version it is more forgiving. http://www.thingiverse.com/thing:2086521

UPDATE 4/3/17
I added a spool flange with only a 98mm OD per request so it can be printed on a 100mm bed.

This is a revision of my original spool holder for ProtoParadigm's five dollar filament which is used to stabilize the spool while printing. The previous version required one and a half turns to thread the flanges together. I wanted a quicker way to assemble it, so I came up with this version that utilizes ball detents instead of threads so only a quarter turn is required to assemble the flanges.
