i printed this at
.2mm layer height
.8mm shell thickness
with black pla. I also changed curas default retraction from 3mm to 4.5mm for less stringing and this thing is louder than i could ever expect!!
My wife works at a public swimming pool and i think its going to work great. The only issue i had is that the model seemed to be at a 1 or 2 degree tilt or it is missing a section on the top right. everything works still but doesn't look as pretty on that one side.
