As some of you Rostock MAX guys might want, the DXF's have the new ORION cheapskate truck plates. They have only 4 bearings, not 5 (no difference in prints but much higher accel is working great), it also moves the u joint mount up for 1" added Z. You could print these out and replace the ones on your rostock max for added bonus points for having printed parts
