Alternatively you can just bang the biggest nozzle they have in there, increase the layer heights/print speed and cut that time WAY down. Larger nozzles tend to make for stronger prints (slicer settings dependent, of course) due to more inter layer surface contact. You're gonna see layer lines either way, they'll just be more pronounced.Like most things in life, the answer is "it depends"... What quality print are you looking for? What printer are you using? Etc. Printing this on my Ultimaker S5 using "Fine" (0.1 mm) resolution, Cura says that the box takes 1 day, 21 hours and 33 minutes, and the lid would take 13 hours and 11 minutes using those same settings. If you are happy with lower resolution, the time will be shorter.
