V40 Mini Grenade | World's Smallest| Flying handle

This is a life-size replica of the V40 Mini Frag Grenade – the world's smallest frag grenade used in combat.  Despite its tiny size, the real thing has a lethal blast radius of 5 meters (16 feet) and an effective radius of 15 meters (50 feet), and since you can carry 2 or 3 for every 1 full size grenade, these have been popular with some soldiers.  The handle is spring loaded, just like my other grenade models, so when you pull the pin and release the spoon handle, the handle flies off, just like the real thing.

( ! ) 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.

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 filaments for the peg spring.

Bambu Filaments used were:

• Matte Dark Green
• Matte Yellow
• Silk Silver
• Polymaker Metallic Chrome

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