That's a cool project. And, no I don't have anything related to those covers.
Sharing a similar experience.
I recently had some non-stock unobtainable internal fork parts made by students at a local tech training center.
The Machine Shop Program Head is friends with one of my Guzzi Associates and made it happen.
I was able to meet with all those involved at the school.
CAD drawings were made and parts produced on CNC equipment, first rate stuff all from students.
I got the feeling that they were much more interested after I shared photos and related information about my project, '74 Police Guzzi with non stock unknown fork internals.

The head of our local Guzzi Club is into 3D printing etc and has made up some very nice replacements for the turn signal stalks used on about all Guzzis since the late '90's I'd guess.
Another club member has a set installed on his side car rig.
Better than the originals by the look and feel.
So, I support this creative avenue.
Getting the next generation into some hands on practical, functional endeavors.
And, it's just damn cool what can be done these days.
