I redesigned the funnel based on my 2023 Lelit Anna with PID. I am still not perfectly happy as the water still spills sometimes, when poured to enthusiastically.
Printed Standing up on left side with support.
Update Jan 2025
Added a 1 mm ridge around the edge and introduced some tide breakers to reduce spillage.
The author remixed this model.
Resized for my Machine. Optimized for FDM Printer.
