Walter is right. When I modified my latest calculator to accommodate a 2.5mm headphone jack, I used a small round jewelers file, and it looks great. For the micro-USB, of course, a small flat file is needed. A Dremel tool, can cut away plastic so fast that a tiny slip, can make a big ugly scar. I have such a scar on my first calculator modified for a 2.5mm jack. (I learned the hard way, but you don't have to. Thanks to the experience shared by those like Walter)
