Lock and Load
I needed a funnel that would lock onto my portafilter so I could load and tamp coffee without such a mess. I like to settle the espresso by tapping the portafilter. I had to hold my old funnel in place using two hands. No more!
Print Guidelines
Print upside down (the project file already has you covered).
Use a food safe plastic. Prusa recommends PET-G.
The project file is configured for a 0.8mm nozzle, so make sure you change to whatever you're using (usually 0.4mm).
The project file also includes a little bit of support material in the flange lock. Use flush cutters to remove it. If you figure out a way to generate organic supports from the build plate, please let me know, but I think it will require another revision of the part.
