About this 3D model

This is a simple tray I made to hold paperclips at work and coins at home. Could have many other uses to hold miscellaneous stuff in a drawer or on a desk or workbench. Inner corners are generously rounded to make sliding out whatever you are trying to get to easy. Base is 75mm square. Created in SolidWorks 2014. I included the SW file and a Parasolid file if anyone wants to change.
