Kindle gridfinity storage box

The base of the gridfinity box has been generated by grifinity generator (https://gridfinitygenerator.com/en/cutout).It has 2 rasters height and stackable.I've created it for my 10th gen Kindle paperwhite, any other models with the same dimensins shoud fit. It has a few millimeters of extra space as tolerance to to fit too tight.I've added a hole to make it easier to take it out from the storage.The model could be pronted without support on my BambuLab A1 from eSun generic PLA. It has 10% infill to save some filament and printing time.
