      Hi Jens,
Heard back from Neon22, hes very happy for it to be released under GPL.
If you can add this to the top of the code you put in the paper:
#
# curve xy co-ordinate export

obviously add your name to those lists since you've modified it.
Thanks

Hi John,
wow, I certainly asked at the right place! Thank you so much for your
efforts, it would be wonderful if it can be released under GPL.
Best,
Jens

Thought it looked familiar. I'm Simarilius in that thread, I supplied
the dodgy original version that Neon22 improved.
I'm happy for the code to be published, I based it off a blog post from
a now dead blog (wayback link is here:
http://web.archive.org/web/20141216062123/http://jumpnslide.tumblr.com/post/...)
...
I have an email from that blog author Jean Moreno confirming he was
happy for the code to be modified/ released under GPL which I can
forward to you if you wish.
Neon22 that modified it doesn't appear to have been active on the forum
since 2013, but appears to have been active on Github and Inkscape.org
recently. I've just tried emailing them via the openscad forum, will let
you know if they reply.
Cheers
John

Hi John,

thanks!

This is the forum post with the improved version of the script:

And here is the original version (same forum topic):
