For all the Coffee-Nerds out there that heard about Extract Chilling your shot of Espresso - try this.

Basically just a triangle to hold a stainless steel or whisky chilling ball and allow the shot to run down easily.

First I made the 75mm Version and figured it may be a little small if you want to use it for bigger cups so i also made a 89mm version.

Simply place on top of your cup, put on the ball and extract your espresso right over it.

The immediate cooling unlocks or locks in a bunch of flavors that would otherwise be lost - so says the theory.

PLA will for sure not work with this for a long time as the Espresso is quite hot - try printing it in more heatresistant materials (i used ABS) but have a look at the biocompatibility - i won't take responsibility for that. Maybe resin-seal it - whatever works best for you to sleep well at night using it :)
