I recently printer the Dremel Box Organizer (https://www.printables.com/en/model/217722-dremel-box-organiser-gridfinity-based ), but I have some additional accessories.
Since the 8220 kit comes with an additional nut with a spot light, which needed a place. Since its opening is not a circle, it will not fit the regular holder for the nut.
Notes: the spotlight is a bit bigger than one gridfinity square, so it needs some additional room on one side. Also, it does not fit all all spotlight version from Dremel (e.g. the one for the 4300 is different and will not fit)
