Remix of the excellent 4 " inch dust separator cyclone from 3D_Blue_Prints. Found the bottom section to be a bit to narrow for bigger planer/joiner chips, so I altered this part. The original has a port opening of 60mm (2.36 inches), my remix is about 78mm (3 inches) in diameter.
This is just the bottom section, check out the link from the original designer for the rest.
Prints with no support.
