Light Gridfinity loose fit lids

I have added lids that only touch on the corners. This allows the lids to be used on divided bins.  The FreeCAD files are parameterized to allow for the generation of other sizes. 

 

These are really only tested with @GlennovitS3D 0.8mm quick print gridfinity boxes. They are meant to be loose and easy to remove and not to seal everything in.  There is a freecad model that you can use to generate other sizes. The smallest is 1x2 due to the finger holes and display pocket. I would suggest printing pocket down with support in the pocket.  You can pop it out if you want to use it. That said I have printed them with out support on a SV06 with PLA. The inside bottom was a little rough but was solid enough.  The pocket also stiffens the lid some.
