Description

A nice upgrade from a generic funnel shot collar that's more compact and allows for mess-free transfer of coffee grounds from a manual grinder's catch cup plus mess-free WDT.

Customization

A pre-exported STL is available for the Delonghi Dedica's portafilter and 1Zpresso J-Max combination, but in the very likely scenario you don't have the exact machine and grinder I have you can open the source Fusion file and customize parameters to make your own custom-fit shot collar:

Printing

  • Print upright with supports on build plate.
  • Insert a pause at the appropriate layer to insert magnets.
  • Post your make! :)
