SAGE Barista Pro Hopper modification

Replacement of the original hopper of the Sage Barista Pro.
I drink several types of espresso, so I wanted to have a small hopper in which I only put the amount of beans I need.

The problem is the locking of the original hopper, this activates a switch, without the activation the machine does not grind.
That's why the creative spring clip.
This is inserted into the funnel from below before installation.

Since this spring clip must be able to be compressed, you should use a material with some flexibility.
i used petg, wall thickness 1mm, 15% infill

Any material can then be used for the funnel and lid.
