Ports for MicroUSB dimensions

In adding a new hole for our MicroUSB port, we have diverged from the previous method of creating a hole without thinking about the dimensions and user experience. We need a way to update our Nodes without taking them apart. To facilitate this, new compatible cases are to be printed with a hole for MicroUSB ports that are 11.5mm wide, and 4mm tall. This extra room is because the port is deeper inside the node than one would think it to be, since our hardware is not flush with the case. We need to account for the room for the cable when inserted so we can put it in without it getting stuck. The dimensioning I did involved me taking sample MicroUSB cables and finding the largest possible cable and giving it .75mm of wiggle room on each side. This will be reflected in the Seimens NX file.
