About this 3D model

This is a mock/dummy hand grenade fuse system, with the dimensions from G&G M18 Dummy Smoke Grenade BBs Container. This model with specific torsion springs, electric switches and buzes can create a working training model for Airsoft and Military in the trapwire training area. I didn't continue creating the other parts of the grenade: body, spoon and so on... The model its complete and working, meanwhile i abandoned this project due to the torsion spring: . torsion spring with little force to hold down the switch button. torsion spring with specific design, it is difficult to adapt an already existing spring to the drawing
