I started with IRobertI's dust filter: https://youmagine.com/designs/dust-filter

The body is thicker and now there is a lip around the opening to assist with alignment when the body is closed.   Also, there is a piano like hinge and increased interference between the body and the clip and different geometry where the clip rests when the body is closed.

The result is a much more positive “snap” clip closure.    It's now to the point that it's hard to open!

To allow the filter to be attached to the printer and ensure it doesn't interfere with the feeder gears, I added a mounting tab, socket adapter and finally ball end stalk that attaches the feeder of my UMO.    The ball and socket provides good articulation so the filter moves as the filament unwinds and is less likely to cause binding and additional load on the feeder.

NOTE:  There are some difficulties in printing the parts.

First, the filter body piano hinge is a "print in place" hinge and requires good bridging ability for the internal structure.    Gently flexing the hinge after printing usually frees up the hinge.

Second, the ball end mount is printing "standing up" so the ball is at the top to ensure the ball is nice and round.    I added supports so the tall print doesn't fall over.   Remove the rectangular support on the three sides.  *** Print this part with support too ***.

Finally, there is a version included without the tab (labelled "No Tab" ) if you prefer to use the new body but not mounted.   The .rsdoc file is also included if you want to modify in DesignSpark Mechanical V2.
