Introduction
The previous Mendel X bracket was compact, but led the toothed belt along a tortuous path with tight radii and reverses of direction. This could cause belts eventually to fail. This design is larger, but less prone to belt failure. It's in the alternative parts section of the distribution (mendel/mechanics/solid-models/cartesian-robot-m4/printed-parts/alternative-parts/) and is simple to print and to fit.
Fitting
The belt teeth face inwards with this design (rather than outwards as they do on the original Mendel). This means that the motor needs to turn in the opposite direction; simply reverse the order of its four leads into the stepper-motor controller.
