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!
3 shells. I printed it in 3DXTech's Red ASA. Print two or more at a time to give the tab a bit more time to cool.
I cut two pieces from a kitchen sponge (NOT the cellulose kind) to fit the case. Add a drop or two of oil to help PLA. Not certain if it helps other types.
Timelapse of three at different layer heights.
I used Onshape to model it, and then about five prints to get it dialed in.
