Portafilter funnel for Sette 270W(i) coffee grinder

thingiverse

My new Baratza Sette 270Wi coffee grinder works exceptionally well. However, some of the ground coffee ends up outside the portafilter basket, making a mess very quickly. To solve this problem, I designed a custom portafilter funnel for my Rancilio portafilter 58mm basket that specifically works with the Sette 270W(i). This design will likely work well with other 58mm portafilters too. After seven iterations, I finally settled on the current version. You can see it in the last picture. I printed the final funnel using 3DE Premium-Silky silver PLA, which looks great. The main reason for the mess is that dry coffee beans can cause static electricity during grinding, making the ground coffee spread and stick to everything. This funnel solves this issue. A trick to prevent the mess is to add a few drops of water to the beans in the hopper before grinding, which significantly reduces static charging.
