US M34 White Phosphorus Grenade with Flying Handle

Summary

Want a realistic replica of the M34 White Phosphorus grenade that has a spring-loaded flying handle when you pull the pin?  This grenade was used in the Vietnam war and has been featured in many games and movies since.

Background: The M34 White Phosphorus grenade is a smoke and incendiary device historically used by military forces for signaling and screening operations. Upon deployment, the device creates a dense cloud of white smoke used to obscure troop movements or mark specific locations on a battlefield. 

Spring options (for flying handle)

1. Metal Spring (recommended) – if you have a metal spring, even a pen spring will usually work, then print the metal spring profile.  It is designed to work with the Bambu Store's 0.5x7x12mm spring (linked lower on the page).  If you use a pen spring, you can usually cut it in half and get two springs.
2. Plastic Spring – if you don't have a metal spring, but still want the handle to fly off, then print the plastic spring profile.
   1. If the spring eventually wears out, just print a new one and pop it in.
   2. Don't leave the spring under tension when not using it as it will wear out much faster.
   3. Avoid Matte and Silk filament for the spring itself, Basic and Metal work better.
3. No Flying Handle - if you don't want the handle to fly off and just want a grenade model, simply print either version and don't put in a spring.

Filaments used

• Black
  • Sunlu Black Silk (Amazon link) or Bambu Metal Iron Gray 
• Green or Gray
  • Bambu Matte Dark Green (used in model photos)
    • A light green would be most realistic
  • Bambu Matte Ash Gray or a similar filament is also realistic
• Bambu Matte Yellow

Metal Spring Version Assembly

1. Insert the tiny peg/plunger into the grenade topper. 

2. Then insert the metal spring the same way you inserted the plunger/peg.

3. Lastly, screw the top onto the grenade body, doing this upside down is much easier. (this graphic shows the flashbang, but its the same style of assembly for this grenade too)

Plastic Spring Version Assembly

1. Insert the printed peg into the topper, make sure it sticks out the bottom, if not turn it until it does.

4. Lastly, screw the top onto the grenade body.  Its much easier to do upside down. (this graphic shows the flashbang, but its the same style of assembly for this grenade too)
