D3D Mega v19.12
Hint: Use this as a Z axis only, including supports for a larger bed. Note that this z axis is designed for the D3D Pro style frame, and therefore does not require the special mounting as the Y axes on the CNC Torch Table v19.10 - whihc uses box beam tubing to mount the Y axes. The Z axis here snaps onto the D3D Pro frame with the clips as shown. Thus, the Z axis here is fully compatible with D3D Pro.
