You mean the guide and sphere that it slides through? That shouldn't matter tbh as is only a guide, the only problem would be if the pipe is bigger than 10mm then it would be too tight.

The new clamp is parametric and everything is changeable, from the hole on top for different size bolts to the sides for different size Velcro.

Edit: I just thought I can make the sphere parametric that will be the easiest way to fit different diameter pipes without having to reprint the whole thing if it is too tight/loose.
