Simple storage box with magnetic fastening

A simple and effective storage box with multiple different sizes. The models print without supports and only require 6x3mm magnets (8 for each box). Each lid has fingernail cutouts at easy end to make it easy to get the lid off.

Simple print the box in the size you want. Pop a dab of superglue in each of the round magnet holes in the base and the lid and press the magnets in. Ensure you get the polarity correct so that all 4 corners attract each other rather than pushing away. At this point I would ensure the glue is dry before testing or the magnets may be pulled out when you try and open the lid.
