Unfortunately no, I disposed them. Failed during the print but I think was because of the accumulated strings/blobs.
After printed tons of tests with various settings I found the ones that suit my Mega-S+Cura:
0.3mm, 230/80C, Fan 5%, 45speed, 5/70retraction, 100% fill, PET-G, almost no strings nor blobs.
230C is below the manufacturer (don't know if is allowed to post brand names here), recommended PETG temp : 235-255. However the printer temp sensor may not be very accurate.
The layers are very well bound, no cracks. It looks and feel like a very strong but flexible build.
