These four M3 x 30mm nylon screws and nuts can be used with the SmartiPi Touch 2 bottom enclosure download. After 3d printing the enclosure these screws can attach the bottom enclosure to the SmartiPi Touch 2 stand. If you choose to make the enclosure shorter, the screws can be cut with snips. They are made of nylon. Four rubber feet are also included. These might ship with no tracking to keep costs down.
