F-150 Extended Cab wire ferrule

I consistently encountered layer separation at the critical narrowing point. Additionally, the cavity turned out to be slightly smaller than my cable jacket. I printed these parts lying flat to ensure the layers were perpendicular to the narrow section, resulting in a squared backing. This modification also increased the part's strength a bit. Note: I modified these designs from the model by hybris1 but there was an error in unit conversions. You will need to scale by 0.39 (cm to inch) to achieve the correct size.
