Slightly modified version of V60 coffee dripper that doesn't need supports (I changed the handle and the bottom part with smaller overhangs and separated rim), you just slide the rim on the body and eventually put glue to the joint if it's not already tight enough.

!HEALTH SAFETY WARNING!

As you probably know, 3D printed parts are not considered food safe so I definitely don't recommend to use it right from the printer but to make some precautions before brewing coffee. For example prusa has nice article about it so please read it.
