About this 3D model
This is a part for the 2021 version of the Picopresso. It is a plastic part that is removed after taking apart the piston and unscrewing the four screws inside. Mainly because Wacaco has already updated the Picopresso. The old material is no longer in production, so I drew one myself, but it hasn't been tested yet. It is recommended to print ABS because the hot water temperature is close to 100 degrees.
