I really like the Small Parts Storage Box w/Gridfinity Tray, but for somethings I wished the boxes where larger. I scaled the parts box to double width so it is still compatible with the original tray. The box and lid works as intended with a nice fit and the box is fully compatible with the original tray. The original part boxes can be mixed and matched with this larger version as you can see in the picture.
The author remixed this model.
Added a double width box compatible with the original system. The new box fits in the same organizer and just takes the space of two of the original smaller boxes.
