Hi
I am interested in converting 2 dimensional images into 3D models. I have sought assistance with this project from some locally, however, to date I have been unable to come up with a viable solution or conversion.
I have attached a sample image for review.

Do you mean changing these into raised line drawings, with just the black lines raised?

Okay, so here are some ideas.
We have found in other work that less is more with these models. There's a temptation to use textures to show color, for example. However, 3D printed texture is really hard to create, because the resolution of the printer is only 1 mm or so. Thus unless your piece is pretty big, you will just end up with a lot of stringing and mush if you try to have fine detail.
A Braille map of a school that we advised on pushed the texturing about as much as you would want to go, by making it cartoonish. But that was a very big piece, as you can see in the linked article.
We would recommend finding pure black and white versions of your drawing. If you have those in .png form, you can drag and drop them into OpenSCAD and it will create a base with your drawing on it. Tinkercad might do that too, but I didn't have time to try it today. That will be sturdier and more conventional to print than getting fancy and printing lines on paper. What do you think?
