Espresso Portafilter Dosing Funnel (Standard E61 brewgroup) "Eureka Mignon Grinder Ready"

I designed a funnel for my ECM Espresso machine, which fits into  a default E61 brew group. The E61 brew group is the most common type found in almost every larger espresso machine.

I created this design to work with the Eureka Mignon Specialita grinder. For this machine, it's necessary to push the small knob to initiate the grinding process.

Materials (magnetic version):

• I added 8 holes (each measuring 5mm x 5mm) for inserting small magnets if desired, but it's not necessary
• Magnets: https://a.aliexpress.com/_Ex1vWhl
• To print with magnets, add an 'E601 pause print' command to the G-code for layer 71 (at a Z-height of 14.2 mm) and push the magnets inside. 

Print:

• 0,2 mm
• PLA/PETG
• without supports (I added some small support parts into the design. Very easy to remove)
• Print direction: Top to bottom
