There is Crashspace in Culver City which does a monthly makerbot meeting (ie work on your own bot). I have only had a chance to go once so far but when I went there was about 6-8 people with bots there working on them and another 20+ people stopped by over the 3 hours just to see what people we're doing. A good group of people, all with a variety of different customizations on their bots. Heby dekekincaid - California, Santa Monica / West Los Angeles RUG
