I had written that desktop foldable cutter one a few months ago for the silhouette challenge in which
MakerSpace.org.uk(our local NCL based hackerspace) was given one and a challenge to publish a number of instructables. However I realised I hadn't yet posted it as a research note. Hope you enjoy it.
At the moment it uses the silhouette software encoding. Should be easish to convert to use it in another vector program.
cheers
