I design simple stuff with OpenSCAD. Then I print it on my batch 9 Makerbot #448.
I have a blog for my Makerbot stuff that is updated every once in a while: http://makerbot448.wordpress.com
Oh and you'll probably notice that I like a lotttt of stuff on Thingiverse. Thats because there's just so much awesome stuff that I want to remember for later.
Come see me at Makerfaire Bay Area 2011! http://makerfaire.com
