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

(update 190224: size 1x6 added. Size 1x4: handle inset corrected)

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. I could not resist, so here it is. Obviously, it is important to print it in food approved material that is also heat resistant. I have only found the 3dkTOP fulfilling both of them, but I assume there are other brands available.
