I have added cura profile.. layer high 0,3 initial layer 0,2 horizontal expansion 0.8 (really .. this is importan for wall thichness. if not.. the wall will be unfortunatly thinner.) initial layer horizontal expansion 0.8 hole horizontal expansion 0.2 prınt speed 50 mm/sn retraction distance 2 mm dual extrusion nozel swich retraction distance 4 mm but not prime tower (if your machine is creality cr-x, the retraction distance should be 16 mm to both of two nozzeles.) I thing the other parameters dosent important but I recommend to you, see and watch, the sliced model with preview, every time after every silicing..
