If I recall correctly, somebody on here was looking for replacement vents for the early Delanair A/C system. Somebody on the 912 BBS discovered firm to 3D print the moveable vents. Passed the info on to me and I am going to reach out to the 3D printer to see how much they would charge to make up a few sets. Any interest still here? Don't know if he could do the actual bracket that holds the vanes, but I will ask. PM me if any interest. Going to reach out Friday. Apparently plastic is dark but somewhat translucent. Might have to paint the actual vent blade.
