Step 2

Add Part Details

Enter part name, description, and print instructions (10-2000 chars each)

Step 3

Upload Files

Add reference images (required), 3D models, and/or 2D drawings

Step 4

Accept License & Submit

Agree to CC BY-NC 4.0 license and submit for review

Supported File Formats

File Type	Formats	Max Size	Required
Reference Images	`.jpg, .jpeg, .png, .webp, .svg, .gif, .heic`	10MB	Yes (min 1)

2D Drawings	`.pdf, .dxf, .step, .stp, .igs, .iges, .xml, .svg`	10MB	Optional

Total upload limit: 100MB for all files combined

Tips for Successful Uploads

Use descriptive part names that include location (e.g., "Driver Side Mirror Cover")
Include multiple reference images showing different angles
Mention recommended print material, infill %, and layer height in print instructions
Ensure 3D models are watertight/manifold for best print results
Double-check year/make/model accuracy for proper fitment matching

Frequently Asked Questions

What file formats work with the 3D viewer?

STL, PLY, and OBJ files display in the interactive 3D viewer with measurement tools. STEP/STP/3MF files can be downloaded but don't yet support in-browser preview.

Do I retain ownership of my uploads?

Yes! You retain full ownership. By uploading, you grant 3DCarParts a license to display, distribute, and fulfill print-on-demand orders. Other users receive your content under CC BY-NC 4.0 (non-commercial use only). See the full Upload Agreement for details.

How long does review take?

Most parts are reviewed within 48 hours. You'll receive an email notification when your part is approved and live in the library.

Can I edit my upload after submitting?

Yes, you can edit your own parts from your profile page. You can update descriptions, add files, or replace existing ones.

What happens if my upload is rejected?

We'll email you with the reason. Common issues include missing files, incomplete descriptions, or safety concerns. You can fix the issues and resubmit.

Troubleshooting

Upload fails or times out

Check file size limits (30MB for models, 10MB for images). Try a different browser or clear cache. Large files may need a stable connection.

File format not accepted

Verify the file extension matches supported formats. Some CAD files need export to STL/OBJ. Ensure the file isn't corrupted.

3D model doesn't display correctly

Check that the model is properly scaled (usually millimeters). Ensure it's a closed/manifold mesh. Try re-exporting from your CAD software.
