=====Fixing .stl files===== Someone sent me a .stl files that Cura doesn't like. Here is an easy way to fix the file. * Go to https://stephaneginier.com/sculptgl/ * Scene > Clear scene * File > add (upload your .stl) * In the right menu bar, under Voxel Remeshing, push it to 400 (the bigger the number, the better the quality, the heavier the file). * Click "Remesh" * File > Save .stl * Done! Now Cura likes the new file.
