USB-c port hole too small

[forrcaho]

Maybe it's just my printer (Lulzbot Mini 2) but the holes for the USB-C ports to stick thru are just a bit too small. I may be able to file them larger, but it's enough so it would definitely work better if the hole in the model were just a bit bigger.

Also I think the hole shape could be changed to accommodate the flat circuit board on top.

Is there an original file format this was designed in that might be easier to modify? If so, and the design program is free to use, I could try to fix this myself.
