There was not a single college dorm bed shelf other than TheSoup's (http://www.thingiverse.com/thing:760369). His bed shelf was meant for a wood loft while my loft is all metal and rounded. I came up with a design that should be able to fit all types of beds with the use of zip ties.

NOTE: ONE SIDE HAS AN EDGE/RIM SO MAKE SURE YOU ROTATE OR FLIP THE PRINT TO HAVE THAT PRINT ON THE BOTTOM

I've uploaded multiple files so you can customize this to fit your bed with the majority of programs available. Make sure to post any photos of yours or your remixes! Enjoy!

This sucker took about 14 hours to print going at 50 mm/s, 0.3mm, 25% infill with PLA. If you use PLA I suggest masking tape and hairspray on the bed so you do not experience that much warping (and also a high heat bed setting, I was at 100C).
