Saw the original model and i liked the whole thing so i scaled it down and also added another version that includes cilinders inside the design to save on filament.
My coffee setup
Casa Brews 3700 Essential
Bottomless and spouted portafilters
Breville Smart Grinder Pro
The author remixed this model.
Made a scaling change and now the measurement is perfect for 51mm type portafilters.
Tested with bottomless and spouted with no issues.
Infill from 10 to 20 is recomended
IMPORTANT NOTE : No Supports needed but be aware there is a cilinder inside the design to save on unecesary filament ( GIF included) If your printer can handle it ( it should) then it will print perfectly with and the cilinder will be hidden and unoticeable.
