About this 3D model
Slightly modified ecksbot X carriage to allow for auto bed level using http://www.amazon.com/gp/product/B005GCM7BC/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1. The probe mount has support posts generated in Meshmixer. The probe cable probably interferes with the stock eckstruder motor. I'll be using it with an E3D hot end and a bowden extruder. I've also added holes for zip ties to better secure the bearings to the carriage.
