Hi everyone,
Like many of you, I noticed that the open vents on the FL5 front fenders are a magnet for road debris. The tires throw rocks right through them, causing potential damage to the side panels. While high-end performance cars usually have mesh in these areas, our FL5s were left open.
I decided to fix this. I started with a design from Thingiverse, but I wasn't satisfied with the fitment. 7 physical iterations later, I’ve achieved what I consider an "OEM-level" fit that meets my standards.
The Design Challenge: The typical flat guards you find online don't account for the complex geometry of the fender hole. If you look closely, there is a 3mm step at the bottom clip and a weird lip near the top. My design includes a custom cutout and offset to ensure the guard sits perfectly flush without stressing the clips or leaving gaps.
Material & Print Specs:

I’m sharing this for the community so you can protect your paint without spending a fortune on commercial kits that might not fit as precisely as this.
Enjoy!

Material & Print Specs:
- Final Version: Printed in ColorFabb HT Black. It’s my go-to for automotive parts—superior to ASA, incredibly durable, and handles high temps perfectly.
- Mesh: Hexagonal pattern with 2mm thickness and 1.2mm walls (optimized for 0.4mm or 0.6mm nozzles).
- Prototypes: I tested PLA versions on casual rides and they held up surprisingly well, so PETG/ASA should be more than enough.
- Honda Part Code: 91512-SX0-003
- Advice: Buy a handful of these on AliExpress or from your dealer before you start. Just break the old ones, install the guard, and use the new clips.
