When I saw this mech walker I had to give it a go. I'd only made one automata before and that was years ago so I'm pretty pleased with how smoothly it runs.
Next up I made this little delorean from Biglobe. By little, I mean I printed the design out several times smaller than intended.
Something that just had to be done was this Aston Martin DBR9. I rushed it a bit at the end so there's a few mistakes but overall a pretty decent outcome for just a few sheets of paper.
