Hi ! My print, of "Modular/Stackable Boxes" by "SkaljicNezir". Slicer: Creality Print v4.3.8.6678 (Win). Printer profile "Ender-3 V3 KE_0.4 nozzel". Material profile "CR-PLA_1.75" modified (Temperature, Printing Temperature: 215.00 °C, Initial Printing Temperature: 215.00 °C, Final Printing Temperature: 215.00 °C, Auto Temperature: No.). Parameter config "Normal" (0.20mm). Scale: 100% File(s): box1.stl After slicing and printing twice, the boxes are not stackable, so I did another slicing with this time a horizontal expansion of -0.15mm ( Advanced: Yes, Shell -> Horizontal Expansion: -0.15mm ) .gcode file: _brim_HorizExp=-0.15mm_box1-Ender-3 V3 KE_0.4_CR-PLA 215_4h30m.gcode Filament: PLA Recyclé ArianePlast File(s): box2.stl .gcode file: _brim_box2-Ender-3 V3 KE_0.4_CR-PLA 215_2h28m.gcode Filament: PLA+ Blanc ArianePlast With this group of models I had several difficulties - Warping because I had not put a "brim" during my first slicing and probably because I had insufficiently cleaned my printing plate... - A partial print of "box2.stl" (the drawer) because a knot on my reel... - And the tolerances were too tight which forced me to redo the prints with a horizontal Expansion of -0.15 mm for "box1.stl" otherwise we cannot assemble them if we print several. After deburring.
