KaffeeWirbel / CoffeeWhisk

Coffee Whisk. 
Geek out on Coffee ;) 

Helps to even out lumps from grinding in the coffee powder before tampering.

Uses acupuncture needles with size 0.35x50mm. 
They can be inserted from top and replaced easily if bent/broken.

Model files contains whisk with top and bottom protection from the needes. 
And a Funnel to avoid spillage.

If your printer is nicely tuned then no support needed. Use layer heigth sufficient fine to for threads. I printed mine with 0.15mm in PETG.
 

To allow the threads open and close smoother add 1.5% in x and y dimension for the top and bottom cap. But keep body dimensions

Funnel is fitting 57mm Lelit portafilter (tested on Lelit Anna). 
To fit portafilters for E61 group head: resize the funnel by adding 4% in x and y dimension (tested on e.g. Bezzera BZ10).
