Nested Magnetic Storage Box w/ Lid

This is my first model to upload to Maker World! I created this to store some custom sized cards I was trying to organize. Realized that others may be able to make use of this as well. Inside dimensions are 108mm x 95mm. The box is 15mm deep, but with them stacked, only about 12.5 is usable. Can be used as just stackable boxes, or can add 1 top lid, or lids for every box. 3mf file includes one box and one lid. Fit is fairly secure, but magnets add extra security. Magnets are 8mm x 3mm and a tight fit. Pictures are printed with Bambu Matte PLA on an X1C. If there's interest in other sizes, let me know!
