That's a great tinderbox you have there!
Confined space. Dry paper. Hot metal.
I don't know what could possibly go wrong.
Not confined open front and back. paper is dry you got me there. Barely warm is more like it. hub is room temp chips on devise are hot to touch but not painful (under ~130F) so nowhere near 451F need to ignite the paper.
