Hey everybody,

Had to change the wall generation to Arachne otherwise the springy Part is not connected to the body.
I wonder how to get rid of the seams on the spring part completely.

Changed the outer Wall to 0,33mm helped quite a bit:

Painted with the Seam Tool to block the Seams, but that doesn’t help at all.

Any Ideas?
