This cyclonic separator is my first THING so be nice. I was wanting to buy a cyclonic separator but couldn't find anything for less the $70 so I took a look on Thingiverse and saw some rudimentary separators. They weren't quite what I wanted so I threw something together real quick. The infeed and outfeed are sized for standard 1.25" hose. I'll eventually upgrade to a larger hose.

I added a couple of specific features:

1. Mathematical dimensions based on the
   "Puu-0_4400_cyclone_calculation_sheet.xls" spreadsheet from Neil Stone
2. Added an input feed down ramp to remove the turbulent dead zone introduced by the infeed.
3. Broke the design into three pieces(bottom, top, and outfeed), with separation between the pieces for simple glue together assembly.
4. Added a support to the bottom to ease mounting the cyclone to a 5 gallon bucket or similar.

Required Additional Hardware:
4 - Size 10 Bolts
4 - Size 10 Nuts
8 - Size 10 Washers

This design printed well on my Prusa I3 and has been eating all my table saw(building a shoe bench) can put out for the last couple of weeks.

1. Print the three separate parts
2. Mount the Outfeed tube to the top piece by pushing through the hole in the upper surface of the top. Try not to sand the piece much here, it is meant to be a tight fit.
3. Use the Bottom piece to mark a hole in the top of paint bucket and cut out the dump hole in the bucket lid. Line up the bottom piece on the dump hole and mark/drill the four mounting holes. Mount the bottom piece due the bucket using the additional hardware. Make sure bucket lid is tight on bucket
4. Mount the Top/Outfeed assembly to the bottom with a small bead of super glue, let dry
5. Mount shopvac hose to outfeed(top port) using a ziptie/tape/or similar. Mount your input hose to the infeed(side port)
6. Suck away
