X Carriage Stepper Mount bottom

Parts for a scratch build 3d printer design. majority of the parts am planning on using like the 8 mm rods, steppers ans radial bearings where salvaged from an old industrial photocopying machine I got from the trash. an Up-cycling project. This first part is the bottom of the stepper side x carriage. the idea for the printer is an XY plotter and moving Z axis Bed Platform.
