3D model description

Enjoy smooth, cold brewed coffee with this print!

After some experimentation and a few clogged filters, I ended up with this triple filter design based on two 1 quart wide mouth mason jars and progressively smaller filters. The cut-away drawing shows the final system stack-up.

The recipe I am currently using includes 1 cup of coarse ground coffee, 2 cups of cold water
in a mason jar, closed with a standard lid and ring, brewed for 6-12 hrs on the counter. I insert a paper filter, made for basket coffee makers (8-12 cup), in the flat bottom filter section, assemble the system and invert to allow gravity to work its magic. To drink, I heat 1 part brew, one part water and enjoy the result hot, but look forward to trying it over ice next summer.

Please be aware there are challenges to making 3D printed objects food safe. If you haven't already, you might use this as an opportunity to educate yourself.

Update : increased the jar filter thickness so that it is more robust

I printed this with PETG filament using a 0.4mm nozzle, and did some clean up on the inside of the filters with an Xacto knife. The paper filter section is assembled by pushing the round bottom filter down through the jar end opening, and seating it in the grove near the opposite end.

How I Designed This

I designed this using Fusion 360 - still learning, but I am a big fan!
