Absolutely! Here's the updated description with your note about the parametric .f3d file:

🎉 Birthday Speed Limit Sign – 3D Printed

A fun little project to celebrate a milestone birthday! This model mimics a speed limit sign but with the number of your choice – perfect as a keychain, decoration, or cake topper.

🧩 Components:

• Main body (white with black numbers)
• Outer ring (typically red)
• Optional: Print in one go with a multicolor 3D printer, or assemble manually from separate prints

🛠️ Customization:

• The included parametric Fusion 360 .f3d file lets you:
  • Change the number (e.g. from 47 to any other age)
  • Adjust the overall size of the sign
• Ideal for making versions for multiple people or party themes

🖨️ Printing Tips:

• Multicolor option: Use the provided .3mf file for printers with multiple extruders or filament changes.
• Single-color printers:
  When printing the main body, you’ll need to pause the print either manually or via G-code before the number layer starts. Swap filament color at that point to create the black number on white background.
• Use standard settings:
  • Layer height: 0.2 mm
  • Infill: 15–20%
  • Supports: Not needed
  • Material: PLA recommended

🧷 Assembly (if printed separately):

1. Print all parts.
2. Clean and slightly sand the mating surfaces if needed.
3. Use a tiny amount of super glue to attach the red ring on top.
4. Let dry completely.
5. Optional: attach a keyring or string through the top hole.
