This is a fun Easter Egg twist on my other grenades – this too has a life-like spring-loaded flying handle when you pull the pin.  Its the exact size and shape of a real egg, and comes in two varieties – pre-painted or white so you can paint it yourself.  With the pre-painted one, print in whatever colors you want, any color will work.

( ! ) Do not sell my prints — I have not authorized selling prints.  If you sell my prints on Etsy, Amazon, eBay, etc, I will find out.

There's 3 ways to enjoy this model:

1. Metal Spring – if you have a metal spring, even a pen spring will often 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).
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.  (see details below for more info about plastic spring)
3. No Flying Handle - if you don't want the handle to fly off and just want a grenade model, simply print the metal spring profile and don't put a spring in it.

Assembly is super simple, here's the instructions for the metal spring and then below that for the plastic spring.

Metal Spring Version Assembly (shows flashbang, but its the same for this grenade, lol):

Plastic spring version assembly (for the mk2 grenade, but its the same idea for this grenade):

Bambu Filaments used were:

• Light Blue Egg
  • Matte Light Blue
  • Matte Yellow
  • Matte White (for the egg shell)
  • Silk+ Silver for the grenade bits
• Shiny Egg
  • Silk Gradient Blue to Purple
  • Silk Gradient Blue to Green
  • Matte White (for the egg shell) (could replace with silk white for more shine)
  • Silk+ Silver for the grenade bits
• White egg to paint yourself
  • Matte white for the egg
  • Silk+ Silver for the grenade bits

The prototype plastic spring version requires no metal spring and can simply be printed.  I would still recommend using the metal spring version if you have a metal spring because it is much more robust, however, you now have the option to print a plastic spring.  If you do print the plastic spring version, keep in mind that the spring can become less “springy” with time unlike metal springs, so I recommend that when you aren't using the grenade that you leave the spring released to increase its lifetime.  Some users have found that Matte and Silk filaments are more brittle, so if you have trouble I'd suggest trying out PLA Basic or even PETG filaments for the peg spring.
