I have a 2003 Nissan Sentra SE-R Spec V (11/02 mfg date) which has a climate control head unit that developed cracks in the plastic tab which held the diverter and temperature control cables in place. I designed and printed these retainers which engage with the nose of the cable clips, allowing the cable housings to be held in place even the original tabs are broken.
Print the retainers on their side so that the nose of the clip will be perpendicular to the extrusion layers of the printed retainers. This will keep the nose of the clip from cutting into part and separating it between the layers.
The printed parts. Notice that the parts were printed on their side to keep the nose of the clip from cutting between the layers when the parts are installed.

This part was designed in Autodesk Fusion 360. See the attached .f3d files if you would like to edit the part.
