My head is just too big for most hats, including the ones sold by Disney. I wanted to have an ear hat, so I used Tim J's model and rather than attaching the plates to a headband, I put them under a baseball cap that fits with the ears on the outside. However, when I used the default plates by Tim J, I found the ears were too floppy because the fabric of the hat could move around. I fixed this by making the ear plates wider, giving more of a base and allowing the plates to be under the hat without the ears flopping.
The author remixed this model.
Made the ear plates wider so that the ears won't wiggle as much if it placed under a ball cap without a head band.
