1:1 Hyundai i20 N Mk3 (2020-2023) Rear Roof Spoiler | Multi-Part 3D Printable Aero Kit

Give your hot hatch the ultimate WRC-inspired, track-ready stance with this 1:1 real-size Hyundai i20 N Mk3 Rear Roof Spoiler! Designed to perfectly match the aggressive, sporty roofline of the 2020-2023 Hyundai i20 models, this aerodynamic upgrade instantly transforms the look of your vehicle.

Printing full-scale automotive body panels is an ambitious project, so this model has been expertly engineered with the 3D maker in mind. As shown in the slicer images, this massive rear wing has been intelligently broken down into a highly manageable multi-part interlocking assembly that easily fits on standard large-format desktop 3D printers. The built-in heavy-duty alignment joints ensure a seamless build, maximizing structural integrity and guaranteeing perfect alignment during final assembly.

Whether you are building a custom show car, upgrading your daily driver, or looking for an ideal rear spoiler alternative to expensive aftermarket fiberglass kits, this 3D printable aero body kit delivers premium motorsport styling straight from your build plate.

To ensure your custom car part survives the harsh elements of the road, high speeds, and extreme weather, please follow these expert printing guidelines:

Material (CRITICAL): Do NOT use PLA! Automotive exteriors face extreme UV exposure, road debris, and intense summer heat. PLA will warp and fail immediately. We strictly recommend ASA, ABS, or high-temp PETG for excellent thermal resistance and outdoor durability. (ASA is the absolute ultimate choice for UV resistance and strength).

Wall Loops/Perimeters: 5 to 7 walls. You want the outer shell to be incredibly thick and robust. The true strength of this spoiler will come from the thick perimeters, not the internal infill.

Infill: 20% - 30% (Use 3D structural infills like Gyroid, Cubic, or Honeycomb to provide multi-directional crush resistance and rigidity against wind drag).

Supports: Standard or tree supports are required for the interlocking joint cavities and the contoured overhangs that mate with the car's roofline.

Assembly & Finishing: Assemble the segments using a heavy-duty two-part automotive structural epoxy or a plastic welder. Once cured, sand the seams completely flat, apply automotive body filler (Bondo) to any gaps, use a high-build filler primer, and finish with an automotive-grade gloss black paint, OEM color match, or a carbon-fiber vinyl wrap!
