Here is a very detailed model of a jar typically used for bulk foodstorage. The 3DSMAX version is fully rigged and animated (see demo video). Nearly all objects are parametric (not collapsed) so that the user can adjust amount of faces used.
It was built to scale using real-word measurements. It was created in 3DS MAX 2013 and uses standard Mentalray materials which can easily be changed. No bit maps are used on the models for hassle free network rendering. The parts are intelligently named and grouped. When possible, object pivot points are placed where they should be for logical animation and parametric objects are left un-collapsed so that you can adjust and animate them, when desired. This model is ready to be dropped into your scenes and rendered.
