<p>This is a line drawing and I would like to print it a couple of mm high. I cannot figure out how to get this line drawing filled. I converted to SVG with Inkscape, used GIMP, took it online to TinkerCad and tried it with Onshape but all I ever get is just the line and this does not work well on my printer. What is a smart way to get this filled in and ready to go?</p>

<p>I use TinkerCad to convert to STL and that works fine. So I could also try to edit the STL in stead of the SVG file.</p>

<p>Maybe I should print the original scanned image (TIFF) and then fill it by hand with black ink and then scan it and convert it to SVG but that sounds really dumb.</p>

<p><strong>UPDATE</strong><br>
I went back to the original drawing and using the bucket tool. The result is a rather noisy image and I need it to be sharp and tight to be able to convert it to a good SVG later on.
Looks like it is more of a graphics design question now..<br>

I\'ve been using the extension for applicable projects with great success. Expect minor complications for closed paths within other paths, however. You may have to create separate STL files for those paths and use Boolean subtraction to remove the "holes" as needed.</p>\n\n<p><a href="https://i.stack.imgur.com/NpFF2.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NpFF2.jpg" alt="Inkscape OpenSCAD DXF image"></a></p>\n\n<p>The extension is slightly counter-intuitive.
