Airwolf 3D printer HD2x XY Blocks & Belt tensioner

Replacement XY Blocks and Belt tensioners for the AirWolf HD2x 3D printer. I have included the 123d files for your modification (non commercial). Left block bearing cap is modified to hit the endstop switch if you are running an aftermarket print head for the Airwolf like the one designed by Josh Swafford available here. http://www.thingiverse.com/thing:956219
