Ford F150 Lightning grill cover

   After driving just 1,000 km with my 2024 Ford F-150 Lightning, I noticed multiple dents on the front heat exchanger caused by rocks kicked up from the road — one of them quite serious. Given that I frequently drive on highways and the road conditions in my area are less than ideal (lots of loose gravel and stones), I decided to design a custom 3D-printed grill cover to protect this vulnerable component.

After several design iterations and careful fit adjustments, I finally achieved a version I was happy with. I’ve now tested this grill cover over approximately 2,000 km (50% city driving, 50% highway), and it has performed very well. No new damage has appeared on the heat exchanger, and I haven’t noticed any negative impact on cooling efficiency or airflow.

Printing & Installation Tips:

• Material: I tested both ABS and PETG – both work well. Do NOT use PLA, as it will likely deform during hot summer conditions under the hood.
• Print Settings: I used 10% honeycomb infill, with 0 top layers and 0 bottom layers . Feel free to customize the pattern if you prefer a different look.
• Installation Method: I used plastic zip ties to secure the grill cover, as shown in the reference photos. Only a few zip ties are needed, and the entire installation takes less than 10 minutes.
• Important Fitment Note: When installing, make sure to press the grill cover downward so it slides into the gap between the bumper and the inner structure — there's a groove that helps lock it in place more securely.
