The positioning of the box is not that best, you get an very ugly toplayer. (picture 1) and also holes (like lines) on the bottomlayer. I positioned it from left to right on the bed, not diagonally- with 2mm brim and get a better toplayer as also no holes on the bottom layer. (Rating has 3 Stars so i can post this now, will give 4 when the print is finished - Makerworld wont let me ;-) ) Alternatively someone who print it can also adjust the fill angle - 90 degrees should be good
