Frank and I are discussing a deck layout for diamond rigs, to allow for complete seamless transition between two hulls, back and forth. This would mean a raised foredeck. No promises yet.
Multicolor printing and PETG-CF are two areas I have not experimented with due to a lack of resources. Tests in these will come soon. PETG-CF is either stiff enough or not.
Multicolor printing could be seriously awesome though.
I do not plan to release printable files until I have completely finalized any changes, and I am sure that nothing can cause issues in home assembly. This may take a few months to a year.
In the further future, I plan to begin a similar project on a marblehead at some point, though this would be increasingly difficult due to weight.
