Thing I made for fun using my SVG to OpenSCAD Bezier extension for InkScape:
https://www.thingiverse.com/thing:2805184

The SVG is from this URL:
https://vignette.wikia.nocookie.net/nintendo/images/d/d7/ARTWORK_-_LINEART_-_Mario_-_CIRCLE_2.svg/revision/latest?cb=20161223045033&path-prefix=en

I have a feeling this might be in violation with some Nintendo copyright... I may have to delete it
