Has one of you the following mast in use and has designed a suitable mast clamp for the Flipsky 65161?

I shared with @jeffM my mast clamp for the V2 alu gong. He adapted it for the V2 carbon gong (8 mm difference.) see with him.
Thanks Manu! I will contact him.

Very nice work JM , the carbon mast with the mast clamp is very nice . And thank you for sharing your adaptation of the mast clamp.
Hi I can write only many thanks! So I dont need my plastiline anymore.
HI, I printed it out but it doesn’t fit the mast. It’s too big. Do I have to change the size (from 100% to ???)
Thanks!
well done JM ! was it hard to drill the mast?
Do you have a picture ?
you have the same mast gong 70 cm V2 carbon ?
I printed without size modification
No it’s easy to drill, but you need a 8X60cm drill
(found on Amazon)

well done! how did you ensure the verticality of the drill? eye balling?
8mm it’s the size inside the mast so the walls guide the way

Hi, No its the 100cm mast… so size is different 
Perhaps the size (width) is different with the 100cm.
How big is it ? you have a picture ?
Have to make a picture. But its not V2 its the mast in Sale https://www.gong-galaxy.com/en/product/gong-foil-allvator-carbon-mast-100-cm-freesurf/
