Does your cup holder rattle?

Make sure to not fill any parts that would restrict the movement of the cup holder
Cup Holder too Small?
I always had trouble fitting Sobe bottles and such in the cup holder. This is how I fixed it.
Before (do not drink and drive)
Mark the area you want to trim away. You should be able to cut 1/8" all around
Dremel around the hole, making sure it remains round until you get to the marks you made
After (with a little more room)
Looks the same, but it now perfectly fits Sobe and other large cups
