Nope. I have printed the calibration tester in PLA+ perfectly. (http://www.thingiverse.com/thing:1363023) I measure 100mm across the points as it should be, and 5mm hole is 5mm. All the shapes and everything else printed perfectly. I also printed a 40mm cube, and this too is perfect in all dimensions.
I am going to reprint the roller that failed, drill out the holes again to 8.5mm then try scaling the feet to fit the tubing.
