Coffee filter holder for 1x6, 1x4 and 102 size coffee filters

thingiverse

Coffee filter holders can be a design challenge. They can be made pretty - eg concave at one side, convex the other, coffee guides at the inside, penguins at the outside. It was irresistible, so here it is. Clearly, printing it in food-approved material that's also heat-resistant is essential. I've only found 3dkTOP to meet both requirements, but I assume there are other brands available for this purpose.
