3D printed Cyclone Dust Separator

I do a bit of wood working and have trouble with my shop vac filter clogging and needing to be replaced frequently.  The filters are $20 a pop and the vacuum is much less effective at filtering really small particles than a cyclone so I designed a cyclone separator  to extract the saw dust more efficiently and keep my filter from getting clogged up.  Commercial separators cost somewhere between $75-200 and this one is just as effective at about $25 including the extra hose.
