I designed this in Fusion 360 within a couple hours trying to make it as accurate as possible. I designed it to fit my monoprice select mini so it is slightly smaller than in game. The grenade could be scaled to 120% for a more accurate size. This is an awesome gadget the operator from Rainbow Six Siege, Smoke is known for in game.

Carefully remove supports. I sanded wherever the supports touched. One of the attached electronic pieces fell off and was very easy to hot glue back in place. I hot glued some non functioning wires and an LED onto the grenade then used yellow duct tape and placed it as accurately as I could on the canister.
In the game the yellow tape is double sided and that is how it sticks to walls so what I did was put clear double sided tape on it and it held up on walls pretty good as you can see in one of the pictures.
