Want to print your own diffuser at home or through a service? This STL pack includes the same geometry used on our functional race diffuser. Designed for modular printing, easy mounting, and durability under high-speed airflow.
Files are oriented and sliced for consumer-grade printers (Bambu, Prusa, Creality). Includes build notes and suggested materials.
What’s Included:
STL files for modular diffuser (split into print sections)
PDF guide with recommended materials, infill, and mounting tips
Optional: Fusion 360 or STEP model as a paid add-on
Pricing:
$75–$100 for STL kit
+ $50 for editable CAD source
License: non-commercial use or shop-use license available
ADD-ON:
Full printed product delivered to your door:
Designed, tested, and used on our own hillclimb car — this 3D-printed rear diffuser is built for function, not just flex. Modular, bolt-on, and print-optimized for airflow. Includes mounting support points, diffuser strake geometry, and aerodynamic rake built in.
Printed in ASA or PETG depending on your spec. Intended for race or off-road use. May require light trimming or custom brackets depending on install.
What’s Included:
Printed diffuser assembly (modular sections for shipping)
Mounting hole template
Optional install guide (PDF or printed)
Material: ASA, PETG, or Carbon-fill (upgrade optional)
