Hmm. I also know a guy who has an vector EPS image file of the logo, but he doesn't have a CAD model of it (and he also doesn't know if it's scaled ratio-wise to fit in the hood liner).

However, I've discussed it with him and he's willing to send you the vector file if you wish to go that route.

I think "that guy" already sent "my guy" that file and he did something like this.

Just needs to be scaled to fit the hood liner. Something "my guy" will probably do tonight.

OK, so after this little discussion, I got looking into converting this stuff for 3D printing.

Now as some of you know, I've been using the free/open program OpenSCAD as a tool to design 3D objects for printing. In a similar vein I had previously used the free/open program InkScape to convert graphics files (JPG, GIF, PNG, etc) into vector-format files for vinyl cutting.

So I'd been trying to import the vector files that InkScape produces, into OpenSCAD to generate a 3D STL file for printing and hitting a number of problems (note, you can surface .JPG files in OpenSCAD, but then you hit the issues of rough edges from pixellation). So while investigating these issues on the ol' interwebs, Lo and Behold, I found there's an add-on/extension for InkScape in thingiverse that allows you to convert a vector outline to an extruded OpenSCAD file! (https://www.thingiverse.com/thing:25036)

This means that not only can we solve @chickenwire 's problem, but you can print a nice 3D version of any graphic (or combination of graphics) for displays, car emblems, etc. (The Sol/Sky silhouettes come to mind).

As an example, below are screenshots from OpenSCAD of a meter-wide (5mm high) version of the Solstice script logo, along with a close-up of an "S" to see the smoothness of the edges. These can be easily scaled down, or up even further, ratio-changed etc. Now, it is a bit of a convoluted, multi stage process to get here, but at least it's doable:

1. InkScape: open graphic; convert to vector, resize as reqd; convert to OpenSCAD file.
2. OpenSCAD: open file from 1.; render; save as STL.
3. Cura (or similar) slice and render to GCode file
4. Print on 3d printer. Iterate back to 1.

Ahhh, what fun!

Nice
I use a tool to import obj files and size them then save as .gcode which I,ports to my printer driver slicer. Works well

Maybe I'm missing something, but aren't your OBJ files already 3D? How do you get a 2d image file converted?

Lol
I did not say two d images

They are 3D models

The printer uses Gcode to print.

I will get more info tomorrow. This is all new to me

Okay, so I'll be less "vague". I've already brought the vector file into my solid modeling software as a 2D sketch. Old trick I learned 30 years ago in the wireframe/surfacing CAD days - you scale that biotch up huge, like 50 times larger than desired, trace B-splines over the outline, then scale it back down to your desired size. That takes any of the jaggedness of the edges out of the model.

From there I can extrude the individual letters to make a 3D solid model. These can be saved in most any format, including STL.

This image is actually a 3D solid model that I was going to "hire" my son to run in renwood on the CNC mill he operates at work. I was going to highlight with paint and hang this in the bay where the Solstice lives. If anyone would like an STL file of it, PM me.
