Filter Pig

thingiverse

I've been using that PLA filter, but why settle for a boring cylinder? There's a slot in the bottom where you can insert a piece of sponge coated with light oil. Almost any cooking oil will work, but make sure the smoke point of the oil is higher than the printing temperature. For example, olive oil has a smoke point of 210C, while refined safflower oil tops out at 266C.
