A retractable party popper toy that uses replaceable and customizable faceplates in place of a blast of confetti

Highlights

• The “string” can be pushed back into the barrel so you can experience the fun of a party popper again and again
• No confetti mess to clean up
• Can be easily stored and reused for other celebrations
• Great for photobooths and pictures since you don't have to time the blast
• The noise isn't as loud as a traditional popper so it could be used in quieter situations
• Additional faceplates can be made to your liking

Printing notes

• There are 4 plates (you do not have to print all the plates)
  • Plate 1 (default: matte white):
    • Barrel engraved with shapes
    • Gear
    • Handle half
    • Extrusion half
  • Plate 2 (default: silk gold):
    • Wavy streamers faceplate
    • Straight streamers faceplate
    • Bolt with star-shaped cap
    • Star-shaped nut
  • Plate 3 (default: black):
    • 2024 faceplate
  • Plate 4 (default: matte white):
    • Barrel with no engravings
• Plates 1 and 2 are sufficient to print the entire model in the cover but if you want:
  • Duplicate another faceplate from plate 2 or 3 so both sides show the same faceplate
  • Print the 2024 faceplate in place of one of the streamers (you may want to print this in a darker color than the extrusion half for visual contrast)
  • Print the barrel with no engravings on plate 4 in place of the barrel on plate 1
• Print the parts: barrel, gear, handle half, extrusion half, 2 faceplates, bolt, nut
