Since the motor is not actually constraining the end of the leadscrew, it
is not as important to have a massively rigid mount. But, with a motor that
size, the combination of torque, belt tension and inertia add up to a lot
of forces acting on it. Something made out of 1/8' thick steel angle should
do fine.
