About this 3D model

12mm X 12mm X 2mm Tiles to test out my dual extruder conversion of my Airwolf 3DXL. "Progress" from left to right. Lesson 1: un-check retract only when crossing perimeters. Still have some work to get my 2nd extruder to work as well as the original one, had a stripped filament that was messing things up and the feed rate is not right. I'm still trying to figure out how to update my Repetier Firmware to get the offset recognized. For now I'm using slic3r to do the offset, but I know that's a band aid approach. I also need to dig around in the firmware to adjust my 2nd extruder feed rate. My home made hobbed bolt bust be off a little because not enough is coming out.
