hard to find in decent shape Damien ... they have a tendency to crack / break in removal ... the sun also takes its toll on them.
question for the group, somebody was talking a while back at trying to remake these - either thru casting or 3d printing ... anybody have any success?

I have access to a set, i'll pm you.
Thanks guys. Yes I seem to also remember someone discussing it, it was just an idea at the time, but they are quite complex. That said, do they need to be complex ? The only bit you can see is what pokes out the dash, if someone could make the top part, it could surely mate to something made out of flexible ac ducting or something. Just an idea that came to mind.
What is a intact set with no cracks worth anyway?
does anyone have one I could borrow?
I think the complexity is that the shape has to turn from the long slot into a round tube, and that has to be located fairly accurately I would think
The are hard to get in, there is hardly any room for them

What’s the plan. I have one you can have. The fins are chipped but the body is intact. I also have a first draft STL file.
sent you a PM
I always end up disappointed with the limitations of current 3D printing technology. I guess to do the entire piece it could work by creating your model, then splitting it into two halves to print. Then gluing them after they're done ?
I don't really understand this, what is disappointing? what would the advantage be of making it in 2 parts? The original is one part and injection molded, you have more (much more) freedom of shape with 3D printing
This can be made in one print. Perhaps the limitation is your printer. It will cost about $300 per side though. The original piece
was made in halves and fastened together.
My thought was to remake the exposed section. 90% of the time the bottom is fine. Just model the top and glue the old bottom to it.

The original one actually have two halves, connected thermally with each other.
plus mechanical tiny rivets
Hi Mark. Sorry that was just a general comment, I've tried over the years numerous times to have parts made and each time there was some technical difficulty, multiple limitations, it was painful. But you could be right, it could just have been the limitations of the particular machines the firms I dealt with had. And perhaps the technology has moved on in the last couple of years. Also, you're right, I can't actually think of a reason why that part couldn't be made in this way so apologies, it would be great to see this work out.
Hey no need to apologize, Inwas just wondering what issues you hit. My biggest disappointment is cost!
It was a while ago, but I remember the part was slightly too big, around 350mm. Then the was the finish which required manual work to smooth it off, and filing off the supports. One part just couldn’t be done because of the difficulty of incorporating supports. Yeah and then there was the price. I’m sure eventually it will become easier, I just don’t think it’s there yet.
I know this thread is hijakced, but @eriknetherlands has a good line on ducts.
I mostly print SLS, which is zapping a bucket of powder. The powder is the support.
SLS also is pretty smooth
Much less stepping but the vinyl has the consistency of a sugar cube.
so it would match the strength of 50 year old, sun dried plastic ... sounds like the perfect material from an authenticity point of view
