portafilter spout (single + double)

This is a single spout for the Gastroback Advanced Pro G portafilter (also available as Breville BES 860 and several other names) designed to replace the double spout that ships with the machine.I've optimized the flow for a smooth, bubble-free output without splashing and stuff. Works quite nice and should fit any portafilter with a M16 fine-pitch thread (DIN 13-5) outlet.Here's a video of the spout in action: https://media.giphy.com/media/cPzpmKf48cEco/giphy.gifedit: I just changed the thing to make it easier to print (without fan for high-temp materials) and produce less bubbles. This latest one was printed in ULTEM 9085 because these made of Green-Tec (+Pro) didn't last all too long.editedit: The one made of ULTEM was leaking due to some inaccuracys on the print, so I've made some further tests. Nylon (Polymaker CoPA) didn't last for 2 weeks and currently I'm running out of materials which is why I half-jokingly tried recycled PET (Filamentive OnePET) which surprisingly makes a good impression.editeditedit: Due to request I made a double spout (rev. 31).edit#4: We've got a new espresso machine at work and therefore we need a new single spout. So I've made a few adaptations and it now fits the Lelit PL82-T (Kate). BTW: best material for that use-case turned out to be Colorfabb HT (similar: fiberlogy CPE HT). It's even considered as somewhat food-safe!Category: Kitchen & Dining
