Honestly I never studied the 3d model itself from a software perspective, I always thought it was my lack of experience printing with 3d resin. Like I said I do seem to recall having tried a different orientation, but there were still issues.
As for other dice types, From using a caliper, there are variations, but I seem to recall they were much less obvious that the D6.
If you don't mind me saying, it still may be worthwhile to verify the models and software.
Thanks again for this great software.
