Printed at 75% scale, .4mm nozzle, .1618 layer height, 30% infill, 40mm/sec speed, 5 top/bottom layers, 3 shells. Requires supports and raft recommend to help hold the immense amount of supports this model requires. Also I would add a few extra supports where the downspouts dump into the bowl, auto-generated didn't have enough. The other thing I would considering doing on this model is to open up and not use supports where the pillars are so that you can see them when taking out supports, it easy to break them and they are a pain to clean around. Note: Don't print this at 75% scale like I did unless your a glutton for punishment, there was almost no room to even get into the middle of the upper and middle track to remove the supports. I actually broke a few of the pillars but it didn't hurt the integrity of the tracks. I would print this at 100% scale if I did a reprint.
