📝 Listing Submission Guide
Follow these steps to prepare your model and media, then upload everything to create a polished listing on STLFlow.
1) Submission checklist
| Type | Quantity | Format | Naming | Notes | 
|---|---|---|---|---|
| STL model | 1 | .stl | final.stl | 
  | 
| 3MF model | 1 | .3mf | final.3mf | 
  | 
| Photos | 8–10 | .png | 01.png 02.png … 10.png  | 
  | 
| GIF | 1 | .gif | media.gif | 
  | 
| Video | 1 | .mp4 | final_video.mp4 | 
  | 
⚠️ Tip: Keep filenames simple, lowercase, and consistent. This helps with sorting and display.
2) Prepare model files
Designers typically supply a .3mf project with 4–6 plates. For your listing, you only need:
- final.3mf with the first two plates only (Keychain and No Keychain).
 - final.stl exported from a single-color plate.
