Need help for magnetic fields grasshopper panel for Uni

Good morning!
My team and I for this semester decided to create a laser cut panel based on a design from grasshopper.
We watched a bunch of tutorials and guides and we ended up creating the code down bellow.
Our teacher gave us some feedback and she said that she want both ends of each meshes that spiral around the points to blend into the surface of the base panel.
The only geometry that accomplices that is the central spiral which is basically the desired result for the final project.
Do you guys have any suggestions?
Here are some screenshots and the GH file

thank you for your time!

ps.sorry for all scribbles being written in greek.Our Uni is in Greece
