Thanks! Yeah my printer might be making holes smaller (probably need to run another calibration), but I just checked calibration on sizes and it's pretty much exact (maybe .5mm off). I loaded your STL model in the sketchup and measured distance between hole centers, it comes up exactly 70 mm, so it seems model is off by 1.5mm
