Hey there, I'm still new to 3D printing and also cura. I imported this thing: https://www.thingiverse.com/thing:2183259 I'm trying to print it but it takes my at least 15 hours. And since it's only the shell my question is if it's normal or not. Because I was guessing it would take 2 hours to print that. Thanks in advance AI3M_Mold_walls.3mf AI3M_Mold_walls.gcode
