OK, glad to hear there may be some answers, because it's puzzling me intensely. Give me a run down of the possibilities and I'll work through
The model is from Thingiverse, 1743145, though I think it's present all over the place. I've been using Cura 4.10 at Standard Quality profile (for Creality Ender-3 Pro) with no modifications, expanding the outer case to 101% to give some freedom of movement for the drawer.
Playing with different quality settings shows the effect does not occur at anything other than a 0.2mm setting, but it is reproduced with CHEP's 4.10 Good profile (also 0.2mm). Using different scales indicates it's perfectly all right at 100%, but 101% gives an extra skin at layer 58/389, whereas 99% gives the extra at layer 329/381. Other scalings may or may not produce the anomaly, but usually at different layers depending on the scale - 97% for instance introduces it at layer 62/373.
When slicing there's a definite pause at around the point the extra skin is generated.
I've tried with nothing enabled in mesh fixes (though disabling Union Overlapping Volumes did mean significantly extended slice times), no change.
What I did note is that the file includes an extra little bit of inner wall where the layer is added, not present at any other layer:
Worst case is that I just dig out my old gcode, generated with Cura 4.9, and make manual edits in there (specifically to enable mesh levelling on the printer) so even if it isn't solvable nothing is really lost.
TIA.
