Actually I wrote following in 3D-print thread. But since I did not get an answer, here again separately, in the hope that this time my question will work out more. I have no idea about 3D-print, so my question may seem a bit naive to the professionals among you, nevertheless… I have the problem with my C70 convertible the problem that the rear window always resolves at one point or another. Glue attempts on my part end with the previously described Erg ebnis. I used the Petec high temperature silicone Matic, before Sikaflex which was already recommended here for such fales. Now my idea was to make a kind of narrow frame, which lies around fabric and disc on both sides and which is screwed through the disc on both sides in addition to the bonding. Can one produce such with the 3D pressure or is the curvature of the disc a problem? Otherwise also an aluminum frame could be a solution… Volvo fabric is in a very good condition does not consider an exchange of the whole top. Thank you in advance for your answers.
