here is one useful thing i designed lately:
Ideal when taking apart some device and you need to store/sort the screws without loosing anything. it has got magnets under each compartment that hold the screws in place, and you can create a lid if you are not reassembling your project at once.

You can as well add magnets to the lids or text in almost any font/style/sze if you want
