Got it.A quick update on the 3D printing. My contact has an excellent 3D printer, but the parts scanner is a low end hand held. I got the AC vent back, and it's sub-par. I haven't lost hope on the 3D printing front, but I'll need to look at parts scanning elsewhere. Shifting priorities to the part-out process.
I might be able to have my friend in Austria scan my intact left AC vent piece. Then it's simply a case of mirroring it and voila - there is your right piece too.
This might take some time though since I'll have to pull the part first and ship it to my friend.
Not sure about the quality of his scans though, since I haven't seen any of his work yet.
