3D Printer / RepStrap

This is actually a work in progress design I am using for building a 3D printer from mostly reclaimed parts and built using common household tools. I intentionally left details out due to my necessity to improvise based on my tool and material limitations - however, this model has proven to be an immensely helpful tool for the fabrication process. I am projecting <$300 in purchased parts. I post updates and more information on http://www.ifthenventure.wordpress.com/ (see 3D printer category).
