After Microsoft retired 3D Viewer I wanted a quick way to look at print files before opening the slicer, so I built PrintView3D. It's free and open source. - Opens STL, 3MF projects (with all objects), G-code, STEP, OBJ, glTF and FreeCAD files - Opens ZIP downloads from Printables / Thingiverse directly, no unpacking - G-code: toolpaths coloured by type, layer slider, print time and filament use - One click (Ctrl+P) opens the file in your slicer. Creality Print, OrcaSlicer, Bambu Studio, PrusaSlicer, Cura and others are found automatically - Export STL from a 3MF project - Thumbnails in Windows File Explorer - Windows, Linux and a macOS beta; one-click updates on Windows I print on a K2 Plus, K1C and Ender 3 V3 myself, so it's tested a lot with Creality Print files. https://github.com/sevagjb/PrintView3D Feedback is very welcome, especially if your slicer isn't detected. https://i.redd.it/5wvdz1vafvxh1.gif   submitted by   /u/sevagj-b   to   r/OrcaSlicer [link]   [comments]
