Summary Here the dead-simplest NES cart cover I could come up with. It prints in about 15 minutes, fits snugly, and makes your NES games easy to store. The left and right sides are slightly wider to increase the overall strength of the part. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.2mm Infill: 15% Notes: Ultimaker 2 default settings worked great for me, no need to up the infill or resolution since the walls are so thin.
