Hi Gaston.
Mark only posts to UK. I think there's too much work involved in receiving payments from abroad and posting, maybe duty etc.? And he can't really accommodate returns and so on.
I feel I must restate that Mark has got involved as a favour to me when I wanted to find a printer for Roger's original design. Being a friend with a 3d printer Mark did one for me and then I talked him into offering them to the talk Morgan folk.
It's not a business or profit making exercise (sadly for Mark) even though he got caught up in my enthusiasm and worked on many prototypes and is still improving the materials etc.
If you had a friend in UK that could order one for you and post it to you privately, that might be a way around the export issue?
All best,
Nick
