SummaryJust a basic Carbon Filter with a 14 mm male and female. When the bulb is filled with active carbon, it really filters anything passing through it. Has a built in screen also. Attempt at your own risk, I would definitely advise PLA because it's more natural and doesn't have the harsh chemicals of ABS but I seriously doubt that it would get hot enough for any chemicals to be released from the plastic. Print SettingsRafts: NoSupports: NoResolution: .15Infill: 30Notes: I'll post a printed one soon but I tried to designed it so that it shouldn't need supports, like I chamfered the screen nipples so the bottom edge is at an doable angle. I'm a little curious how the wrapped triangle will actually print but I bet it'll work.
