3d printing for design

Good morning to all,
a customer commissioned me the creation in 3d of 2 dowels to make it thick to a spoiler of a sports car.
In this case I also have to design the dowels creating the 3d design. I am expert especially of 3d printing and I am now facing the solid modeling. so I would like to ask you a council, especially procedural rather than specific controls of a parametric design application (in my case solidworks).
I hope to be able to make the idea with words and images because unfortunately it is forbidden to insert the 3d model of the design (it is a spoiler of a prototype car).
In practice I have to produce two lids (of the shape equal to the two rectangles of white color that see in the attached png, in the third image in baso), which go to thicken and divide the two parts that make up the alettone. This dowel is also slightly curved in development because as you can see in the first image above there is a crack between a piece of the wing and the other.. this because the external part must be mobile).
the question is: what logical and practical procedure would you use to create these two dowels (which measure both 50 mm long for small thickness of 3 mm)? I apologize for this question... but the sw commands now as now I begin to use them well and if there are problems with them I go to read the guide... but I still miss the experience for the logical part of the design process.

Thank you!

do you care to know in solidworks?
if it is so part of knowing how to produce it.
For example, if you produce it in 3d printing, it makes no sense to use the sheet module.
if the profile to be obtained is complex you can use the surfaces.
working directly on the sample do 3d sketches and new reference plans; for such particular objects it is difficult to establish a strategy also because we have 3 images, but it is not clear how they should be interpreted, the second seems a section from above, but the third?
 
If you have to model only the dowel do a sketch of the perimeter and extrude it of the "desired thickness"tassello2.webp

I imagine that those of the images are simplifications, otherwise even for those who know little about solidworks make an extruded like that is banal.
it is also specified that it is slightly curved (in which direction we do not know) and according to this curvature can change the modeling process; Finally, it must be circumstantial to the sample on it should be applied that having curved surfaces does not have its precise references, but should be created
 
Good evening to all and thank you for the answer. I made some changes to the image I had attached and in green I marked where the thickness should be inserted, which must be quite precise.. I mean, it's got to take over the premises. In practice the image above is the view from above, the second is a side section while the third at the bottom is the enlarged section to better show the blue sheets that create the seat for the dowel that is represented in a white background. the program I use, confirm, is solidworks 2019.
Okay then start by creating the section... but how do I develop in a curved way following the direction of the hollow seat (which is seen marked in green in the first image above)?
I hope I've been able to clarify the situation better!

Thank you!

to get that particular there are more roads:
- sweep function (if the profile is constant)
- loft function (if the profile is not constant or you need some control not present in the sweep command)
- two extrusion functions (one to get the vertical leg and one to get the horizontal one)

for the sweep you need the profile to l and the curved path
for the loft you need the initial and final profile and one or more guide curves
 
Thank you!
eventually I could create a parallel plane and adjacent to the spoiler and then make convert entities after selecting part of the curve... and then use the projection of the curve as a guide for the sweep.
Tonight I try!

So... after several tests, I arrived at this satisfactory result. the most difficult thing was to find the right combination of reference to create plans!
Anyway, I'm asking for help. once I created my solid by modeling it on the step... I should save him, always in step format... but I should only save the solid that I created (grey color indicated by the yellow arrow in the image I attach) and not along with all the existing multibody. Is there a way to do it without having to eliminate the previously existing bodies?

Thank you!

Thanks massive, always help me, I'm grateful.
If we don't hear each other, I wish you a party.

Hello stefano,
if you may be interested, after you have finished the project, we can realize you the part with xxxxxxxxxxxx

Thanks, but I am a professional printer, the doubt was on the drawing, not on the printing.
