Rain generator

After I watched these video on Robert Murray-Smith TnT channel :how to make a Rain fuel generator (droplet-based electricity generator ) https://youtu.be/JWHl4TLM9TY
and the following improvments https://youtu.be/Mp8mMu33mNk
I want to make a rain electric generator using my Laser Induced Graphene LIG electrode .
The 3D printed supports for electrode and contact are intended only for mechanical resistence , because the LIG electrode on kapton tape is printed on a 22x22mm glass microscope cover glass 0,13 mm thickness.
To print the LIG electrode I use a NEJE DK-8-KZ laser engraver, I modify it with grbl following this video https://youtu.be/u5aXPjorQcM
First rain generator was LIG electrode, ptfe tape and aluminium tape electrode 0,2 V

Second rain generator I simply turn the LIG electrode and used its glass support 0,3-0,4 V

To print the graphene electrode I use octoprint bettergrbl
