Basic Coffee Moka filler

Since everytime I fill my Moka with coffee I make a mess, I designed this funnel which adapts to the diameter and height of my 1-cup-moka.

There are tons of different moka designs so I included the drawing. As you can see the inside diameter is 41mm. Just measure the diameter of your moka (in millimiters) and divide it by 41 and you'll get the XY scaling factor for your model. Z can be the same

Have a nice coffee!
