Small Box With Magnetic Lid
This is a 60T100W60D box to store various things in it. The walls are thick so it should proove to be really durable.
For the lid I used magnets that I crazy glued in place. The magnets I had are 6.4mm in diameter. They will hold anything in place. And if you want to open the lid you just slide it off the box.
There is another box similar to this that gave me the idea to use magnets (thing 59332), but thats where the similarities end so I made a new thing.
