58mm portafilter funnel, compatible with (at least):
Lelit XMC022 (normal)
Lelit XMC028 (bottomless)
Should fit most 58mm portafilters though.
update (13 Nov 2018)
New design especially for those who have the Baratza Sette 270wi (probably also for 270/270w and maybe 30). Will fit perfectly into the hold for 0 spillage.
Opening will accommodate even the largest tampers destined for VST baskets so you can tamp without removing it.
Should fit many 58mm portafilters but it is tested only with lelit naked/spouted.
Design1 : plain with vertical outer wall, will work with all grinders
Design2 : slightly bigger funnel, will work with most grinders
Design3 : larger outer wall than 2nd design, no optimization for grinders
slim: more difficult to print (overhangs ~60degrees) but faster and uses less plastic. Bigger funnel than previous designs but might have issues with grinders with a button.
slim v2: similar to slim but at the end I reworked the funnel in order to work properly with most grinders.
lip / nolip : the lip files enclose the top of the basket lip so you can avoid coffee spillage outside of the basket. But you might not want that if you do the WDT and/or if you want to tamp with the funnel on.
thumb / nothumb : Secure the funnel with your thumb and tap/knock as hard as you want !!!
Print upside down and use raft/skirt if necessary
Sette270 file needs support.
All others: No supports needed if you printer can handle 60 degrees overhangs.
Tested it with PETG. PLA might be a tighter fit but should work ok.
