IMPORTANT: rendering will be better for analyzing the model if fast-csg is enabled. As of writing, this feature is only available in the development builds and not the official release of OpenSCAD, but it makes rendering only take a couple seconds, even for comically large bins. Enable it in Edit > Preferences > Features > fast-csg
