Filter Sieve

This is for filtering liquids using a mini 4 cup coffee filter. It's basically a coffee filter basket but has a bottom add on section with a narrow spout to direct the fluid into a smaller flask or beaker.

Alternately you could use a coffee filter basket or this Strainer funnel by mathgrrl

Its drains quickly because the large flat bottom exposes a large surface area and because the filter doesn't need to be folded. The bottom section is purposely made with only one direction grid bars touching the filter, this minimizes the contact area to maximize flow through the filter and hopefully reduce the amount of liquid retained.

The funnel is printed large side down (with the spout pointing up). The shallowest angle is 49 degrees from vertical so you can print it without supports but you may need to tell your slicer this.

The basket is printed with the sieve on the bed, again without supports, the bars are an easy distance to bridge, only 3.6mm, and the sides taper at 24 degrees from vertical so no supports are needed
