The STL files are example output from parametric Fusion 360 source to define a slide top box consisting of multple, user defined, spaces, each with it's own slide top lid. 

The example files are for a box with 4 spaces, each 25mm wide, 40mm long and 20mm high. Floor, side walls and lids are 2mm thick.  End walls and seperators are 3mm thick.   All these values can be customized by modifying the model's user parameters.

The interior edges of the container spaces are radiused for more easy retrieval of small items.

Fusion 360 model source is provided, as are STEP & STL files for the example.  A local copy of Fusion 360 would be needed to create customized versions of the model.
