The Rod for my towel rack snapped right off the brackets that held it to the wall! So I printed some new ones. They are adjustable based on the spacing of the screws, and provide a cutout on the back for the screw retainers that happened to be sticking out of my wall.

This is my first design. More info about my thought process here: http://jeremyblum.com/2011/06/28/my-first-useful-makerbot-print/

I printed this on a Thing-O-Matic using Print-O-Matic stock settings.
