Is this a laser cut mask or 3Dprinted? I wonder whether the mask has some sort of geometrical error that generates a bias.

Funnily enough if I focus using HFD measurements and go back to Rigil Kent, and put the mask back on, the spikes are even less aligned than that second image. Unfortunately I didn't screenshot that.
It's a mask made of thin metal, so I assume laser cut.
