Hello Michael,
fine, this workflow. I was able to do it. I wasn´t fully happy. Because this is a Logo of a product and it needs to be as near as possible on the original shape.
My workaround seemed to work also. Must wait was the milling company says - but I hope it will go on with my version. I didn´t bend/flow/attached the hand not anymore on a half circle segment. I made a quater segment. And now I got a much better result - not fully perfect...I will see...

Here a first prototype of a former try...
Thanks and best regards...
