Can you help me with the easiest case mod ever?

I want to very slightly widen the hole for the headphone jack on my phone's bumper case. What is the best way to go about doing this?

Thanks, MeFites!

Am I missing something? What's the difficulty? Just drill it out, no? Even a hand held drill bit would be able to cut into that material I'd have thought.

You might want to use a sanding cone drill bit like this one to help control the size of the new hole.

A Unibit is the best thing, but a bit expensive for one-time use.

I did this by scraping it with a small paring knife.

If the plastic is hard enough, I'd try a Tapered Reamer, which is cheap and handy to have around. It also pretty much guarantees circularity, which may be aesthetically important.

I mean, if this is a semi-pliable case (I can't tell from looking at the photo), a drill seems like overkill to me. Get an X-acto knife and do your thing.

Maybe just stick a sharpened pencil in there and rotate. This was how we used to loosen up 33 1/3 vinyl when a new LP record stuck to the spindle, back in the day.

Pliers type paper punch.

Heat up a reamer with a cigarette lighter, stick it in, and rotate it a few times so there's a slight amount of resistance. Go slow - you can't un-enlarge a hole.

Alternately they have lots of skinny inexpensive 3.5mm plugs at your local swap meet/eBay/

Came to suggest a punch, but you want a belt hole punch. Get a piece of shit one at like harbor freight, or the home depot "HDX" brand. it can easily cost under $5 i bet, possibly even half that. I think i've seen them at daiso japan for $3 before...

Open up a pair of scissors, stick one of the blades in the hole, and twist it around a few times so the sharp edge scrapes off a thin layer of plastic from the inside of the hole. I used to do this all the time before I had access to things like drill presses.
