Dog hair, dust, and other small bits might get pushed through your extruder compromising, or completely wrecking a print. After designing a couple filters that were simple slotted cups, I wanted something a bit more refined and lightweight. So I modeled this. Has holes to drop in a bit of oil if need be.
Printed as one piece. Should hinge should be loose or break free with minimal force.

If you this helps and want to encourage my insanity, buy a cup of coffee for me, a bag of coffee, or you pick the value. Thanks!
