Keep your small electronics project safe with this 2 piece ABS plastic enclosure by Hammond. This 1551 series box measures 50 x 35 x 20mm and has two mounting standoffs in the bottom half. These are large enough to fit a small microcontroller like the Adafruit Trinket or QT Py series along with a few other bits and pieces.

Hardware for the lid is included and consists of two Phillips screws. Best of all, this box is IP54 rated, meaning it is effectively dust proof and will protect against water spray from all directions!
