Simple Hepa Filter

After reading how 3d printers shed micro particles into the air, I whipped up this quick hepa filter to make our workspace safer.

The fan I used is pretty swank, but any old 4" (120mm) computer muffin fan should work as long as its the right distance on the screw holes.

NEW: Now with 120mm fan cover. (This is a remix from https://www.thingiverse.com/thing:2832234)

NOTE: Make sure your fan blows out the end and not into the filter.

Here's the fan I used: https://amzn.to/2KieQTW
It has a power controller to set fan speed.

The filter is a "Ausanat Air Purifier Replacement HEPA"

The only esoteric parts I used were 4, m4x180mm studs, when combined with m4 acorn nuts and aircraft nuts hold it all together nice and tight. The nuts can be sourced from your local ACE.

Assembly: Stack it up, put an acorn nut on one end of the stud and thread the other end through
