This is my take on the storage box from Pred.  I've changed the lid to a half gridfinty and this goes along with my Gridfinity boxes I also made:  [https://makerworld.com/en/models/994764#profileId-970860](https://makerworld.com/en/models/994764#profileId-970860)

I wanted to be able to make a bit wider variety of boxes than standard gridfinity allowed so I redesigned the lid to accept half-gridfinity boxes.  The bottom of the box however is still a normal gridfinity grid and this works for both the half-gridfinity and full gridfinity boxes.  Making this box compatible with BOTH gridfinity and half-gridfinity.

The lid will fit the original boxes found here:  [https://makerworld.com/en/models/160167?from=search#profileId-468797](https://makerworld.com/en/models/160167?from=search#profileId-468797) so if you want one of the other 5x5 sizes he offers know that it will fit.
