M6 Steam pipe extension for coffee machines to use with a classic Pannarello

thingiverse

Steam pipe extension for coffee machines that come with a short steam pipe with an M6 thread. This part allows you to use a classic Pannarello instead of the Cappuccinatore the "bigger" machines usually come with. The part should work on most models from Eugster/Frismag which include Bosch Benvenuto, Siemens Surpresso, Nivona CafeRomatica, Krups Orchestro, Krups XP, Melitta Caffeo series, possibly others with the same small M6 thread as well. I bought my machine used, without the Cappuccinatore attachment and never got around to replacing it, mostly because of the time-consuming cleaning necessary after each use. A friend then brought up how nicely the Pannarello on his portafilter espresso machine worked, so I decided to try that way. This adapter extends the short pipe so that the Siemens Pannarello (#60053) fits and works nicely. The outer diameter is 8,8mm which sits snugly in the Panarello and leaves 3 possible shells for the thread area. Print standing up, the top and bottom 5mm (where the thread is) with highest possible quality (0,08mm works fine), the rest can be done at 0,2mm. Also use a heat-resistant (at least 130°C), food safe material! I used Extrudr Green-TEC Pro for mine. Note that the chemicals used in decalcification of the machine might damage this part over time. Better check if it is still okay afterwards.
