Hello, I'm designing and printing curved marble tracks; the curved pieces are split into tiny segments, and the segments are rotated along the curve and raised tiny bit (vide first image.) Each piece is symmetrical to mimic an almost perfect curve (vide second image.) I'm using Tinkecad to design the curve. For some reason the walls of the track only print in segments and not make a long curve (vide third, fourth, and fifth image.) Is there a way to print the wall without printing each segment one at a time, but print in a long curve and thus get rid of extra time and the vertical streaks on the walls? Thanks.
