Paradroid: how I did it

It all started when I found some drawings of the character of the infamous computer game from the 80's.

The next step was obvious to me, just build a raster graphics of the beast using GNU/Octave. As is the original image needed some modification on order to be 3d-printed.

print -deps -color paradroid.eps
print -dpng -color paradroid.png

So added some extra squares to get the job done.

Then used the Inkscape-to-OpenSCAD plugin and got the final 3d model, after some editing on the output code.

And it prints nicely with a resolution of 0.2mm and a 20% infill.
