Even though I don’t own a Kraken(ATM) I really like this project and think how it can be improved.
I’ve seen 3d printed templates that helps placing the antennas in certain distances based on frequency and it reminded me of the expanding pulley mechanism(https://www.youtube.com/watch?v=LU77kPf25Yg) which could be used to adjust the distance using one gear
I think the “spiral” and multiple tentacles fit the brand
As I’m not an owner nor experienced in cad nor have the tools I’m not going to approach it but some should deferentially go at it!
Of course it could further be motorized and auto adjusted based on frequency etc…
