This is a chainsaw shield inspired by Doom: The Dark Ages, which also doubles as a fidget spinner. What's special is that the teeth extend when you spin it, just like the real shield. With the ball bearings used, the spinner spins for quite a long time. I recommend olive green as the main color, along with gray, red, and brown. Measures of the recommented Bearing: out diameter 22mm, inner diameter 8mm, hight 7mm.
The author marked this model as their own original creation.
