Tiny Fidget Grenade with Realistic Flying Handle

Want a tiny fidget grenade at your fingertips? This model is a "working" tiny replica of the famous WW2 Mk2 Pineapple grenade. It works just like the real thing in that you can pull the pin, release the handle, and it will fly off. There's an optional keychain attachment too. Assembly is super simple, just insert a spring from a pen/pencil and then screw on the printed top.Almost all pen/pencil springs work that I testedAny 4mm (or smaller) diameter spring (like a pen spring) worksI recommend you cut the spring to 10mm (~0.5inch) so that it fits better and you get 2 springs for more grenades :-)If you don't have a pen spring, (Amazon link) has a spring that's exactly the right size, or you can get a Bambu spring linked down below.Bambu Filaments used:Matte Dark GreenMatte YellowMetal CopperSilk+ SilverIf you are looking for a life-size Mk2 Grenade, you can get that here: https://makerworld.com/en/models/913462 Here's some assembly instructions in case it helps:1
