This funnel solves the problem of coffee falling out of a moka pot. By rotating the funnel, the specially designed blades smooth the surface of the coffee and slightly tamp down any excess coffee.
This model is designed for the 3-cup moka pot with a 65 mm external thread diameter (see the schematic image). To fit a different size moka pot try scaling the model in your slicer by the factor:
"Required external thread diameter in mm" / 65 mm * 100 %
For example, if your external thread diameter is 55mm, you can try scaling by 85%, for 42mm - 65%.
