About a year ago, I lost my Eddie Bauer water bottle, similar to this one:

I've been trying to find a replacement, but it seems they've discontinued the model.

With that in mind, I'm planning on purchasing this bottle:

Unfortunately, the nalgene doesn't have the molded grip which so endeared me to my original bottle.

So..I'd like to mold them in!

The amazon page says the bottle is suitable for liquids in the range of -40 to 212 degrees Fahrenheit

My question is:

Should I heat the whole bottle up and indent the desired grip with a cool implement, heat up the implement and press it into the bottle, or some other solution?

An ideal answer would not only provide justification for the proposed method, but also suggestions on the most feasible way to enact it.
