3D print an Altoid tin via MAKE. pandelume writes -

This is a makerbottable altoid tin-like enclosure for MintyBoost XL found at thingiverse.com/thing:2144 Will presumably also work for other similar devices. It’s not necessary in the strict sense, but if you can’t find an altoid tin you have a ready replacement. Additionally, you can alter the files to print a design or logo on the lid (in relief and thin lines only, since the top of the lid is on the bottom of the print), and you won’t have to worry about insulating the board from the metal case.
