Fire Alarm Pull Light Switch Cover

I got bored of doing problem sets one night and decided to break out the calipers and CAD the fire alarm pull outside my dorm room. I added a recess in the back of the pull handle so that it fits over my light switch in my dorm room, and I've had a lot of fun pranking friends with it. Hopefully other DIY'ers can have some fun with it as well! Disclaimer: Please don't mount this in a public place or near other, real, fire alarm pulls!
