I am new to pour-over coffee making and lack much of the basic equipment.
I found two Corning/Revere gravy separators in my wife's kitchen cupboards, so I recruited one of them as a “poor-man's” pour-over kettle. The spout on the separator tends to dribble, so I decided to try to print myself an adaptor.
The Pourer 35 by NicoConex was almost ideal for my needs. All I had to do was measure the internal diameter of the separator's spout and model a small cylinder that I could “jam” far enough into the spout to stop the water leaking past the adaptor. I merged the cylinder with the original pourer to make this one.
NOTE: I also cut the pourer on a 30 degree slant, thinking it would mate with the face of the spout. The cylinder is a tight fit about 15mm before that slanted face reaches the spout, though. Rather than continue to develop the model, however, I decided to stop while I was ahead. When you print this model, I recommend that you select “Make overhangs printable” in the slicer (Cura offers this option, anyway). That way, no supports are needed.
The author remixed this model.
Downsized the spout and inserted a 12.5mm x 40mm stem into its base, so that it fits into the spout of the Corning/Revere Gravy Separator.
