Print nozzle 0.4mm, layer 0.2mm, two walls, function: "inner wall correction needed". Infill 8% ( 10mm square) is enough Use Brim for better adhesion. No support needed, even the lid printed well w/o support. Thanks to the nice cat from LOUBIE (https://www.thingiverse.com/thing:2690075), I used as a handle of the lid. The lid fits w/o gears or other locks, if scale 100% is used.
