The M-85 flash grenade is a Toy/prop featuring a hollow inside for storage.

Makes for a good prop or decoration for military enthusiasts or, if you need a flash for an airsoft field.

The assembly is easy and it requires no tools I hope.

You will need a 1mm pin to hold the striker in place and a torsion spring to make it actuate.

I recommend printing this project 1 piece at a time.
