PLA (white color is voluntary because I intend to paint it before offering it)
I added columns on the spirals to avoid using media (for my printing , I unfortunately broke the 2 spirals by removing these columns, the tinkering is seen a little on the picture). I have modified the columns on the shared version to limit this problem.
Resolution: 0.20mm (more accurate is prettier, but necessarily longer)
14h printing !!! (When one loves, one does not count!)
