Black ramps - a way to 3D print them? (Starbucks Barista)

The black ramps on my Starbucks Barista Espresso machine are broken. (The little plastic things inside the grouphead / brew head, where the portafilter locks in. ) I know this part is no longer available online. I'd like to try 3D printing a replacement part. Does anyone know of a source for a file of a 3D model for either the black ramps or the grouphead?

Alternatively, is there anyone with the skills to create such a file?

(I have seen quite a few people trying to find a replacement part in this forum!!)
