Wheel and Axle "Kit"

    A test of part group printing was made using a set of driver wheels and the corresponding axle.  Green ABS was used (did not have the correct black on hand).  The parts are shown at completion on the printer bed prior to removal.
    The white grid at the bottom is the PLA raft that provides a flat surface for printing the ABS parts.  The axle between the wheels has some PLA support material near the bottom due to the presence of a keying indentation that required support material.  The wheels also have some support material particularly under the counterweight portion between the spokes and under the spokes as those portions require support to prevent the ABS from sagging while hot.

    The photo at left shows the ensemble of parts located on the printer bed of the BFB-3000 3D printer.  The bed is in the lower position to provide access for model removal.
