【Red Bull Racing】Red Bull 2025 F1 Car RB21 Livery Assembly/Articulated Tires

【Special Notes for F1 Models】

1. The author has conducted structural printing tests on all models before release. However, the F1 model has a complex structure and requires high printing precision. Newcomers are advised to use the parameters in the slicer directly for printing and not to adjust them arbitrarily to avoid printing failures; experienced players may ignore this reminder.
2. The printing effect of the model is affected by various objective factors such as equipment, filament, and environment. If you encounter problems during printing, you are welcome to contact me through comments or private messages, and I will assist in troubleshooting. Creating is not easy. Please communicate before evaluating and do not give low scores at will; malicious negative reviews will result in being blocked. Thank you for your understanding!
3. All models from the author are tested based on Bambu Lab printers, and the configuration files use Bambu Lab's official slicing software. If you are using other brands of printers, it is recommended to adjust the parameters according to your own equipment's slicing software and preview before printing. Thank you for your cooperation!

4. As multi-color printing becomes the trend, the model is sliced with the H2C multi-nozzle printer by default. For other models, please refer to your own model for slicing preview to check the time and filament consumption.
5. Thank you again for the recognition and support from fellow enthusiasts. I hope to receive your likes and boosts. In 2026, let's unlock more F1 models together!

【Read Before Printing!!! Warm Tips】

It is strongly recommended to print the single-color configuration first before printing the multi-color configuration to test the model structure and slicing effect (Cost of single-color model printing: 64 scale 15g filament, 2 hours. 43 scale 50g filament, 3 hours). After being satisfied with the model's appearance, articulated structure, and slicing effect, then print the multi-color version. Thank you.

Note: Before printing the multi-color configuration file, you can enlarge it according to the complexity of the paint scheme. Preview in the slicing software to check the details and ensure printability.

---------⇪3D Printing Instructions-----------⇩ Product Introduction--------------

Following the F1 Ferrari SF24, comes our second F1 car.
A fan previously requested a Red Bull F1 car, so we created this one, featuring 25 liveries based on the original RB19.
If you have other car models you'd like to see, please leave a comment; I will endeavor to accommodate your requests.
Red Bull officially unveiled the RB21 on February 25, 2025.

Model Description
- Features comprehensive interior and exterior components: front and rear wings, suspension, seat, steering wheel

- Includes monochrome and multicolor print configurations: monochrome allows for painting and decal application. Multicolor prints directly (higher material and time consumption), but can also serve as a reference for monochrome painting
- Articulated wheels, glue-free assembly. Based on 2022 standards, 18-inch rims. Specific dimensions: front 305/720-18, rear 405/720-18. Corresponding 1/32 scale: front 9.5/22.5-14.3, rear 12.7/22.5-14.3

Dimensions
- 1/32 scale
- Sliced files utilize minimum printer dimensions. Adjust the number of multicolor models printed at once based on your printer's dimensions to save time and materials

- The body and wheels utilize bearings for connection; variations in printers and materials may result in looseness or tightness. Print the MR105 bearing assembly components (various gap combinations) from Sampan1120 - MakerWorld for testing and suitable bearing replacement

FDM Print Settings
- The physical model uses an A1 mini with a 0.4mm nozzle, 0.16mm layer height, and official PLA Matte and PLA Basic. Other materials may result in shrinkage leading to looseness or tightness; use sanding or 409 adhesive if necessary
- Infill density: 15%
- Supports: 25° angle. Given the model's small size and potential for scattered parts, use print-in-place. A combination of regular and tree supports is employed. Due to the extensive support structure, utilize cutting pliers and tweezers for careful removal. Use 409 adhesive for any breaks
- Adjust parameters based on your printing experience

Multicolor and Monochrome Printing
- The multicolor configuration consists of multiple parts and cannot be directly monochrome printed; otherwise, surface seams will appear. For monochrome printing with subsequent painting, or structural confirmation before multicolor printing, download the monochrome sliced file (monochrome print time 5h, approximately 60g of material).
- Multicolor printing has significant time and material consumption. The current configuration utilizes system-recommended multipliers. Adjust based on your experience to save material, but not excessively to avoid color bleeding

- Multicolor printing tip: Manufacturer logos are detailed, and the livery is rich, exceeding four colors. Consider simplification, replacing with primary colors, and using decals for intricate details
- Monochrome printing is possible using acrylic paints
- Future releases will include various liveries. Stay tuned for updates

Livery Reference

- Sanding:(Optional) Sand in 400-600-800 grit sequence

- Painting: Use acrylic paints and brushes (for edge layer bleed, apply base coat first, then edges)

- Polishing: Use a soft cloth for polishing to enhance acrylic paint sheen

Assembly Instructions
- Refer to exploded diagrams or videos for assembly
- Suspension links, steering wheel links, and wings are delicate; exercise caution during support removal and installation

- For enhanced durability, wheel clearance is minimal. Tires require slight force for installation and can be rotated into place
- Suspension links, steering wheel links, and wings are delicate; exercise caution during support removal and installation
- Damaged parts can be reprinted individually

If you have requests for other car models, please comment; I will endeavor to fulfill them.

Your feedback on printing results is welcome. This project will be continuously refined based on your input to ensure a superior printing experience.
