Summary

I made this filter holder to fit inexpensive, pleated paper coffee filters.

This general style of filter can rest on almost any convenient container. But the one I had is made to fit the cone filters, like Melitta. Cone filters are better quality, but seem to be finer (at 20 microns ?), and it takes longer to filter things.

I only needed to coarsely filter (cold) deep fryer oil into quart-size plastic containers, so I whipped this thing up. And the operation is pretty quick, filtering the big junk without taking all night to do it.

This thing will sit on containers with a maximum opening of 4 3/4 inches diameter (120 mm). Capacity is almost 16 fluid ounces (450 ml).

The internal filter support-screen is designed as a separate part, and is removable, just to make it easier to wash up.

Metric and SAE provided.

Using Afinia defaults (0.3mm layers, average speed and quality), the filter body required 4 1/2 hours, 122 grams. The screen part took about 30 min, 15 g ABS.

I printed one with external support (for the lower portion), and another without support, and couldn't detect a difference in quality. If the shallow 30 degree angle at the bottom of the filter causes trouble, and your printer can't build that angle without dripping filament over the edge, then give it some support.
