Outer Spiral:

The size configuration was printed at 0.2mm layer height, and printed relatively fast, but there may be some very slight overhang curl. All example pictures are printed at 0.2mm layer height, you might get a silky smooth motion, you might not.

It seems to depend on the filament type/color. All my tests at this layer height have been perfectly fine, but some have slightly more resistance than others.

The best quality configuration was printed at 0.08mm layer height, which takes significantly longer to print. This produces smooth overhangs and the most perfect motion.

Inner Spiral:

Layer height doesn't matter much, it does not affect getting smooth overhangs. It prints perfectly at 0.2mm layer height, no curl, but, to get the best quality, it would still be printed at 0.08mm layer height using the best quality configuration.
