I needed a crimp tool holder that was 6U tall for the gridfinity storage box by Pred. I revised this to be 2x5x6 and to have a little looser fit.
The author remixed this model.
The gridfinity boxes were changes from 2x5x3 to 2x5x6. I also opened up the outer permitter for a little looser fit and changed the cutout to go below the handle for easier removal of the tool.
