This is due to not having enough features , each feature need to be at least 8cm apart from another feature .
You need to use Body Mode and in case of this object probably a standard mode /not High Accuracy mode .
Also when you are in Body mode set the range from 300 to 1200 mm
How far you go how less features you need to be in FOV .
If I was doing it , I would use my white cube magnets and stick it 8cm apart on the most flat surface and scan it in sections and merge later .
The gyro only help capturing the first frame position in space , the rest of the frames follows the position and need tracking features to align proper like a puzzle, if there is no feature in area of 8x8 cm to hold too the frames sliding out, creating the snake effect .
Nothing wrong with the scanner or software , it is the object …
