Use arachne wall generator for much clearer legends (dynamic line width)

Most printers can do twice the resolution in the Z axis compared to the blogger's post, or the same layer height with a 0.4mm nozzle (legends would suffer)

Very minor fuzzy skin enabled on the outer walls can replace layer lines with more of a textured look

ZAA (Z anti-aliasing) post-processing scripts can eliminate most the need for angling at 45 degrees
