OK so I am taking the interior of my 68 and making it a 69. I have a re-manufactured 69 dash some Dakota Digital gauges new Radio and even Astro air vents new column and so on. I didn't want to kick this project off with out having a 69 center vent and the rear duct (I don't like how the vintage air center vents and the ones mounted under the dash that came with my car look.)
After trying and failing to find a re-manufactured 69 center vent assembly I tried finding used one with about the same amount of success and when they are available they seem to go for around 300 ish and the condition can vary greatly.So I decided that I would make my own! I have the dash I have the vents that go in the dash and I have pics from on-line for how it should look. This was also a good excuse for the wife to buy a 3d printer.
I have had the 3d printer for about a week now and I have done a few tutorials for a CAD program so last night I decided that I should see what I could do. I took a few measurements from the vents and the dash and made what you see below. I had to make a few assumptions about where the vents are located and where the lever is and how big its opening is. but I think it looks pretty good. I am going to look at it a little more closely make some minor adjustments and thicken it up a little.
I am breaking this down in a few design stages a few of them might end up over lapping. during the design stage I am using a PLA filament. when I have the final piece I am going to either use ABS or another material that can stand up to the heat and cold that this will see being in a car.
1: Front plate
2: Front plate with the dash mounting points
3: Add the parts that will hold the vents
4: extend the assembly and add the door
5: make the linkage for the lever to control the door.
If some one reading this has an original 69 center vent assembly and has a caliper I could use a couple measurements mainly how thick the center support is between the vents and the relationship between the vents and the left and right side of the dash opening. same thing for the lever opening and how big the opening is.
Thanks and I will keep you guys posted ( Sorry about the last two pics being upside down.)
