58mm portafilter (70mm basket) magnetic funnel/dosing ring

With this design I aimed for a perfect fit, with a minimal intrusion of the inner part of the funnel into the basket and the coffee bed.

The low version is perfect for containing the mess when doing WDT.
The medium variant is best if you want to grind directly into the portafilter.
The high version is recommended if you want to shake and distribute the grinds directly in the portafilter.

Print in the provided orientation ("upside down") - this provides optimal bed adhesion and print quality.

Magnets are optional, but highly recommended, especially for the medium and high versions. You will need 8 4x1mm magnets. They can be push-fitted or glued in if necessary.
