Was looking to learn a bit about working with Inkscape and SVGs and @WildZBill showed me how you can take any SVG and affix it to a shape in OpenSCAD (as you can see, we've made some coasters in this way). I found this SVG online (so, nothing original) and just wanted to experiment with multicolored prints. Super cool! Later on, I plan on doing some metro maps like this (though, multi color lines will be hard!).
