Filament Spool Sprocket (Quick Change) - Bolt with conical bearing seats by ej0rge

Last crawled date: 3 years ago

Quick remix with conical rather than flat bearing seats. This way it is easier to print and there is no possibility of seizing the inner ring of the bearing cartridge against the body.
Should work just as well for people who use this design without bearings too.
For easy bearing fitment you may need to scale this model to 101% or 102% in your slicer depending on the accuracy of your printer. The bores are 22mm but printed in PETG they came out to 21.5mm measured with digital calipers.
10/3/18: Uploaded slightly improved version. I hadn't noticed that I'd increased the ID at the top slightly which would affect people who use it without bearings. Also trimmed the little ridge at the end of the threads off.
