This is an alternative x-motor-assembly bracket as used on Nophead's Mendel 90 machine. This one leaves the stepper motor uncovered. If you experience splitting/delamination of the original, you may want to try this one for size.
Because there is no motor 'housing', the build time is also reduced a lot (approximately 4 hours - depending on your machines setup) .
There is also provision for a 'tie-wrap' to be used on one of the linear bearing, if so desired.
