Smaller parts of Huxly in stl files that could be

Hi there,

I have some problem with stl files of Huxly parts. After that I print x-motor-bracket at another 3D Printer, I see that is smaller then could be (in confirm with motor). And Repsnapper told me really smaller sizer that could be. I test size on some part of original Huxly - that is smaller too, and with Prusa Mendel - where size is right. Could you help me please, what kind of scale i must set to right size, or which is right size of this part for example ?

Thanks a lot !

PS: printing size calibration is right
PS2: stl files which i test is from official github

Ok, my mistake. Huxley is projected with Nema 14 which is smaller in all sizes
