As you can see I now have some cookies cooling down. I'll think I leave the decorations for tomorrow. So, it you can't tell what the cookies are, it'll be revelated at 19th.
About the printer, I think I got it
Addendum (19th) : Well, the printer was kind enough to make those cutters ok, but the next bigger print failed (at early stage)... Ah well.. repairs are part of the learning process here.
