Coffee drinkers that enjoy cold brewed coffee might be interested in a new device which has been created by Instructables user JON-A-TRON and offers the ability to 3D print a six flask cold coffee brewer.
Once constructed the cold coffee brewer is capable of brewing six flasks of coffee at a time allowing you to try out six different kinds of beans in a single process or create 6 cups of cold coffee for your friends and family.
The cold coffee brewer is constructed from 39 3D printed parts together with boiling flasks, needle valves, filter funnels, silicone stoppers, and wooden dowels. The designer of the awesome and very unique looking brewer explains a little more :
Most of the large batch slow drip cold brewers I’ve seen use a large volume of water and drip into a large volume of coffee. This clearly makes economically and simplifies fabrication, but I liked the idea of being able to brew multiple kinds of beans at one time. Like wine snobs, coffee snobs have provided us with a wide variety of flavor profiles and if you pay attention, you’ll notice drastic differences in the taste of one bean from another.
I designed the piece in Fusion 360 (my go-to free 3D design and CAM software). 3D printing is a breeze with this program, making my life a lot easier with so many parts. I explored the idea of making a linear one (the all-to-common setup at your typical hipster coffee bar), but I thought a radial design would have a nice effect, and would also make the brewer more of a centerpiece. After all, the whole point of taking all this time to design and fabricate the thing is to draw attention to it; to make an event out of the slow process of cold brewing.
