Female Micro USB cutout

thingiverse

I use holes for micro USB sockets a lot in my 3D printed electronics projects and needed an exact fit, so I measured with the calipers, threw those measurements away and proceeded to print about ten different sized holes in squares until I got one that was a tight fit. The winning size is x=8.4, y=2.9, z=4.5 with a 0.6mm corner radius (the calipers measured 7.5x2.4!) which is what this thing measures. Basically ```difference()``` this hole against an object, like the wall of a project enclosure. Note that this part is the hole for the female socket to fit into, so its bigger than the male plug. The female micro USB sockets I'm using are [these](https://www.aliexpress.com/item/20PCS-MICRO-USB-FEMALE-SOCKET-CONNECTOR-MK-5P-5PIN-180-DEGREES-vertical-DIP/32852083437.html) vertical ones. The DIP breakout board I connect the USB sockets to I designed in [EasyEDA](https://easyeda.com/sej7278/usbbreakout), this is where the 4.5mm height comes from - its basically the space between the end of the USB socket and the top of the PCB. I also made a version using the [BOSL](https://github.com/revarbat/BOSL) library, see the screenshot which shows it cut out of a square - one of the test prints actually. For this the library seemed a bit overkill. **I know this is basically a rounded cube, but the importance and why I'm sharing it is the exactness of the fit when printed.**
