In addition to the printed part, installing the cable guide requires 1 M3 12 mm hexagon socket head cap screw (ISO 4762), 1 M3 drop-in T-nut for 3030 aluminum extrusions and 1 zip tie (same type as the other zip ties already used in the printer). The printed part has notches to place the seams, so that they do not end up in bad places. After this cable guide is installed, the PTFE tube will no longer collide with the motor cable as the Z-axis moves up and down.
