Parametric storage box with lid in FreeCAD

Just set the needed width, height, depth, wall and lid thickness and it will generate storage box for you with a simple lid.
See the video instructions [here.](https://vimeo.com/361084920) To make objects in FreeCAD visible, hit space. Then export the generated box and lid one by one.
There are 2 versions, one with cutout lid, and another with lid of constant thickness.
