I have not done this
It sounds like you are looking at doing this for emotional reasons. Ideally I think you’d be addressing both the emotional and the math side of things, so consolidating the three cards to something with a lower rate so you are paying less interest over time.
My guess is that if you consolidated you would need to have one card that you paid off monthly for the day to day spending, so you didn’t accrue any additional interest on that, and then have your consolidated debt in a second spot which you only pay down and never use.
This would only work if you have your spending under control enough to use those two cards as above, and you’ve addressed whatever it was that ended up with over 10k in cc debt.
I’m guessing the other approach is to snowball in some way - take the card, put them in an order that is pleasing to you (smallest amount to highest, or highest rate to lowest, or most emotionally draining to least, whatever you think will work from a motivation perspective), pay off the minimum in each card, and put everything additional into the card that is first on the list. Then when you have paid the first one down, do the same with the next card, and then when you get to the final one, you have all the money going there.
