Missing walls when slicing #4
Description
When slicing body_part_a.stl, I'm getting missing walls. I've tried with a few different slicers (SS, PS, Orca) and I've run into it with each. I've tried with thin walls on/off, arachne on/off, different extrusion widths; am I missing something obvious? The only way I've been able to get it to not have holes is to reorient the part per the original commit.
Corner is bottom left as seen here.
Reoriented, no missing walls.
