Trouble with getting a Airfoil to work properly

I am making a Airfoil for a plane I am making in a engineering class I am taking and I am having difficulties getting the airfoil to be all 1 part and having in generate properly in Prusa slicer. I can't get the wing to all be 1 part and have it not completely break its self when I set the printer setting in Prusa to Spiral Vase. If anyone has some ideas or knows what I'm doing wrong I would really be grateful because I have been going crazy trying to figure it out myself. I can attach the videos I have been using if you want to know the process I went through.
Here is the document I have been working in.

Why are you making that lattice in Onshape? (boolean1) Seems that should be a slicer infill setting rather than modeled in. (assuming you're going for FDM 3D printing.
else if you really want to force the slicer to put perimeters there with these cuts, then make sure they don't go through the outside, but leave a solid perimeter (or 2) around the outside.
Im making it in one shape for the class I am currently in. So the slicer infill is the problem?
I am using light weight PLA which requires a singular path to prevent stringing. Spiral vase mode removes generic infill so I am creating my own.
Can you make your document public?
I have some thoughts as to why you're getting individual printed parts but easier to study if I can make a copy.
Sure Ill do it right now
Alright its public.
In tab copy 2 is 1 solid for the slicer to deal with as suggested by others and let the slicer produce hollows if it will.
Both samples are using "edit curve" to clean up the faceting of profiles to generate clean lofts with no facets. The imported data uses an stl or something that can't make clean curves. If you know the foil designation there are some airfoil feature scripts that will to a better and cleaner job of producing the foils. No transforms either. Best when profiles ares located from origin so they won't move later.
In tab copy 1 worked through your method some what or as close as I could. Putting in the ribs was kina brutish but ended up as one part for the slicer. The original had some sort of flaky bits that may output as multiple parts to slicer.
Hope this helps.

Thank you so much. It looks great, but the reason I used spiral vase was to make sure that there was no overlap in the print and to make it as light as possible. The airfoil you made has a lot double lines that makes the wing really heavy. The current airfoil you gave me would use 138 meters of filament, weight around 400 grams and would also take 27 hours to print. Know a way to fix the double line issue so it can be lighter?
In Orca slicer, which I believe is based on Prusa, or at least similar, Spiral Vase mode has to be hollow with an open top. Only one wall.
Sorry if I am misunderstanding your intent.
Adjust variable "thickness" as needed. To adjust rib thickness separately a new variable will be wanted and applied to extrude/thicken. I left the overall thickness at 1mm for clarity during the build but that can be adjusted to what ever you need.
