I took some time to put together a 3D printed Jack-o-Lantern, which was the perfect candidate for customization. So here we are. I can't wait to get my hands on some orange ABS!
Step 1: "Sketching" my 3D design
I went with a slightly "low rez" styled pumpkin which was easy enough to recreate in OpenSCAD.
When I am designing a model in SketchUp that I plan on converting to OpenSCAD I try to use only the primitive solids that OpenSCAD has built in. As you can see in the attached screenshots I used mostly cylinders to create the shape of my Jack-O-Lantern, which made it pretty easy to transfer over to OpenSCAD as cylinders are a built-in primitive.
