The strike zone for this knockbox is the portafilter's handle. This will let you release the full espresso puck and maintain the puck's shape for no other reason than for aesthetics.
To prevent damaging your portafilter, Press Fit the Strike Zone Pad at the top of the knockbox.
The knockbox will still work without the TPU paddings.
