I compared your belt thickness to the Gates GT3 Design Manual, specifically this image from page 9 and everything looked fine.
Sorry about that. I had realized that my belt model wasn't thick enough so I changed it and then realized that I had about .003" of space between the belt and the "roof" of the tube. I found 23T GT3 pulley stock on SDP/SI and decided to make that change since it gives me enough roof clearance (.043") and still gives me room for the bearing counterbore.
