I didnt find 626 bearing required by original model so I slightly adjusted it to accept 608 bearings.
Small insert is needed which also works as a cover so the coffee is not in contact with the bearing.
If you dont use the 3mf file you need to add a 8mm brim for the insert. The brim works as a cover.
Thanks for the original model.
The author remixed this model.
Adjusted for 608 bearing
added insert with cover for the bearing
