There have not been any intentional mast wall thickness changes.

At this time we are still looking for the cause. It can even be that the extruder decided on a different extrusion speed as to be able to pump out more extrusion per hour and optimize his earnings. The builders and myself are just as much behind "the curve" as the customer like you are.

That is why I want to get to the bottom of this weight difference issue as I have said in private communication.
