Sorry to dissapoint you guys but that is not in the possibilities as Axel wrote that in the first post
thought I tried to make that clear from the start
on the other hand now we discussing it , it would be fun to make one ourselves
but that will mean casting , I know a produkt that maybe could be used for it
and wich is transparant not translucent (thank you for clearing that Martin)
and it becomes very hard
I don't know yet if it is suitable for casting , need to check
