i agree as you would think CC would catch this issue. Everyone loves the idea of aluminum hangers thus one would think CC would thoroughly check before releasing. Being machined aluminum it looks like they assumed perfection was acheived as usually is the case with machining parts out of T5 or T6 tempered 7075 aluminum. This obviously is a major over site in the CAD design and thus machinig is producing the cad file it receives.
XRAY needs to fix as if another company makes hangers which XB4 owners will buy and then they happen to find out the actual price to produce relevant to the mark up you will see more disappointment towards XRAY.
There is no problem paying another companies high mark up for providing a solution to another companies faulty part and thus no consumer will have an issue with that but they will have an issue paying so much money for a part XRAY could easily correct and reproduce free of charge to people whom bought XB4 kits or hangers. This would not XRAY cost XRAY much.
