This project is for everyone who owns two items:

• The coffee grinder Sage Smart Grinder Pro (and similarly build ones)
• The espresso coffee machine Lelit Anna (and similarly build 57mm Portafilter Systems)

I have found a similar design and have adopted it to fit those two machines exactly.
If you want you can remix it with the provided STL file.

My print settings are for Black PETG from PRUSA. With PETG you do not have to worry about a hot portafilter.
I think it will also work with PLA but be aware that the portafilter shouldn't be hot anymore if you go for this option.

Support: YES - Tree - Automatic
Layer height: 0.20mm for maximum strength

Orientation on print bed: Print it so that the slots point upwards for maximum strength
