Female Micro USB cutout

thingiverse

I frequently use holes for micro USB sockets in my 3D printed electronics projects and needed an exact match, so I measured with calipers, discarded those measurements, 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 subtract this hole from an object, like the wall of a project enclosure. Note that this part is the hole for the female socket to fit into, so it's bigger than the male plug. The vertical 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) and they're available in large quantities. The DIP breakout board I connect the USB sockets to was designed in [EasyEDA](https://easyeda.com/sej7278/usbbreakout), this is where the 4.5mm height comes from - it's 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 excessive. **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.**
