Cupcake bushings replacement

I finally worked up the courage to upload this thing. Now, let's just say I have my reasons. If you're looking for a reliable solution, I'd recommend using real bushings or one of the many other great alternatives already available on Thingiverse. I'm particularly fond of this one: http://www.thingiverse.com/thing:4213 by twotimes. For those who are curious, the stock bushings only lasted through about 2 pounds of printing before they needed to be replaced. Perhaps I wasn't lubricating them enough. These emergency bushings have held up much better, printing around 10 pounds worth of plastic, but I'm starting to think it's time for a replacement. If you'd like more pictures, check out my Imgur album: http://aubenc.imgur.com/bushings.
