Issues with alignment of thin objects

Hey there

I am pretty new to scanning and just bought a Einscan SE as my first scanner. I plan on (mostly) scanning thin walled objects (~1mm thick car body shells in 1:24). Overall I am really satisfied with the scan results. I get a lot of details but still have one issue. The alignment of the inside and outside. I put the body on the rotating plate and it does around 30 scans in small steps. All good. But the single scans where the scanner sees the inside are not aligned with the scans of the outside very well. I am not speaking of multiple scans in which I reposition the Object but one “continous” scan where the scanner rotates the objects itself.

Is there a way to improve this? The misalignment is around 2-4 mm. So not just a few tenths.
