About
A funnel to help filling 58.5 mm protafilter baskets without spilling any coffee grounds.
It features magnetic attachment to the portafilter basket. It's designed for baskets with a round top but should also work with flat topped baskets.
Due to the magnetic attachment this allows e.g. tapping or shaking the portafilter with the funnel in place to settle the grounds.
This is the second iteration of this design. My first version featured locking prongs but they turned out to be a bit fragile over extended use.
Printing Instructions
You will need up to 20 magnets of the dimensions 2 x 5 x 2.5 mm. These should pretty widely available online. If you want to use magnets of different dimensions, see below.
The magnets need to be inserted during the print. The provided gcode file already has a pause command inserted at 26mm (which is where the slots for the magnets are located).
The easiest way to insert the magnets is by using the entire stack of magnets (as delivered) and using them to press in one at a time.
CAD Model
I modeled this in OnShape. The model is public and can be used to create your own modified version, for example for differently sized magnets (there are variables defined to make this easier).
