This Aston Martin AMR21 racing car is offered as an assembled display project. The inspected scene includes the complete open-wheel source car, four tyres, cockpit, halo, suspension, front and rear wings. Its presentation retains the supplied dark green livery, pink accents, black tyres, carbon-like lower surfaces and original sponsor artwork. The cover shows a proposed completed miniature display; it is not a photograph of a physical print produced or tested by the publisher.

COLOUR AND SOURCE APPEARANCE
The presentation uses the supplied native RGB textures and source artwork. The inspected whole assembly is upright. Where the FBX importer used a source texture channel as body or tyre transparency, that presentation opacity was corrected while retaining the original RGB paint artwork and all original files. No individual component was reshaped or repositioned, and no new sponsor graphics were generated. No manufacturer endorsement or real-world functional specification is claimed. Existing surface detail is retained; source markings may be simplified in the compact colour viewing copy.

DOWNLOAD CONTENTS
The ZIP includes the editable FBX surface scene and Blender 5.2 project, any supplied textures, the full-resolution upright coloured 3MF, an English preparation guide, a file inventory and the locally generated presentation image. Geometry, UVs and materials are verified by reopening the FBX in Blender. Absent optional bitmaps are not invented. The image replaces the earlier reference photograph. The manifest lists only the supplied files, their sizes and their current integrity hashes.

COLOUR VIEWING COPY
A separate upright 3MF contains 168,871 triangles from 22 inspected surface mesh objects. Triangle connectivity and coordinates are checked after export without surface decimation. A compact per-triangle colour palette approximates the presentation materials. Texture lettering, transparency and complex native shading are not reproduced exactly in that palette. The editable FBX and available texture resources are included in the ZIP. Maximum span is normalized uniformly to 150 mm solely for viewing. This is not a verified source scale or a certified fabrication dimension. Scene objects are not equivalent to printable part counts.

GEOMETRY AND ASSEMBLY
The illustrated arrangement is assembled for display. It does not establish that every surface is watertight, independently printable, detachable or mechanically functional. Check thin aerodynamic elements, halo, narrow suspension arms, tyre edges and wing supports. Imported meshes can contain open boundaries, overlapping surfaces, disconnected small features and walls unsuitable for a given printer. Repair, thicken or separate a working copy where necessary; retain the originals as references. No physical print, fit, structural strength, rolling mechanism or articulated motion has been tested.

PRINTING ADVICE — UNTESTED
First confirm slicer units, overall dimensions, build volume and minimum wall thickness. Inspect thin aerodynamic elements, halo, narrow suspension arms, tyre edges and wing supports at the actual intended print size. Choose supports to protect visible body surfaces and allow access for removal. Consider separate working copies for delicate wheels or projections only after checking their connection geometry. Resin layers around 0.03–0.05 mm or FDM layers around 0.12–0.20 mm may be starting ranges for suitable geometry; they are conditional suggestions rather than tested presets. Print a representative fragile section before committing to the entire scene.

SCALE AND FINISHING
No native physical units or real-vehicle scale are certified. Use target length divided by current measured length multiplied by 100 to resize after confirming units. If an original 1:N scale is independently established and a target 1:T is desired, use N divided by T multiplied by 100. Recheck thickness and clearances after resizing. Remove supports carefully, test primer on a sample and mask existing paint boundaries. The suggested finish is the supplied dark green livery, pink accents, black tyres, carbon-like lower surfaces and original sponsor artwork. The display base and surrounding presentation are illustrative and are not extra printable scenery promised by the download.

IMAGE AND RIGHTS
The cover is made locally on this PC using ComfyUI/Qwen from a render of this source geometry. Original boundaries, coloured areas and dark details are retained with a local surface mask; the final image is checked against that reference. The asset is free under CC0 following the uploader's explicit redistribution authorization. Original authorship has not been independently verified from the package.
