3D-printed material is not good quality. Not a good resin, not even PETG for FDM-printing. It's much smaller than expected, and it is very catchy when turning, because tolerances are not observed to, and there is no post-processing at all. No sanding down edges that could prevent it. I'm afraid all puzzles from this brand have exactly the same problems, because they are all from the same material.
They couldn't even make it black, which would be way more enticing, at least. Not worth it.
