Gridfinity Grid for A3 Really Useful Box

This model provides a grid that fits in the bottom of an A3 size Really Useful Box, to allow Gridfinity bins to be put inside for dividing up storage. We use this for taking equipment and spares out for our IT/networking business. The model was created using Gridfinity Generator (https://gridfinity.perplexinglabs.com/) and split into 4 plates in Bambu Studio. I've uploaded it for people who are new to 3D printing, so they don't have to learn everything themselves, and can just use it for their storage. There are four plates to print to allow it to print on a 256x256 printer. The large border around the outside allows the use of 10U high Gridfinity bins that fit snugly inside the ridge of the lid of the Really Useful Box, keeping everything in place.
