Nắp Gridfinity cho khay bins

This is my version of the Gridfinity Bin & Lid system. For me personally, the lid didn't hold tight enough. 

There is the standard version with the four magnet holes in each corner. 

I also designed a version with a single magnet in the middle of each part. 

I modified the design so I could add magnets in the lid. 

The Magnets are 6mmx2mm. For those of you who don't want to use magnets, just "fix" the model with the internal magnets.
