Cyclone Separator for Smaller Printers

thingiverse

I've been itching to design a genuine cyclone dust separator that can be printed in pieces and assembled, but all the models I found were either too small for my needs or too large to print. So, I created this model by adapting the specifications from the first image, which are widely accepted as the industry standard according to the laws of fluid dynamics (I researched it online). Following these parameters resulted in a relatively tall design that should provide optimal performance. This project is still a work-in-progress and hasn't been printed yet, mainly because I've run out of PLA filament and my next roll is a different color. However, I can think of no current issues with the design. I've included a vacuum port adapter for the hose that enters the spiral, which is specifically designed to fit a 2.5-inch hose end commonly found in Rigid Shop Vacs from Home Depot. The inside diameter of this hose measures 53.2mm, and the adapter is intended to fit snugly within it (though I haven't tested its fit due to printer tolerance limitations). The dust inlet has a 2.5-inch ID and may require an additional adapter for proper installation. I've provided the Sketchup file so you can make any necessary modifications as you see fit. Please let me know if you identify any problems or improvements, as I won't have a suitable window to print it for a while. UPDATE: 1/13/17 - A geometric issue on the dust inlet was fixed, and updated STL files (Dust Inlet.STL, Upper Body Upper Half.STL, and Cyclone.SKP) were re-uploaded.
