About this 3D model

Lets be clear this is a laser man bracelet. Not a bracelet. However women can wear this if they choose. It still is a laser man bracelet. I was trying for masonite chain link\\\\\\\\\\\\\\\'s however I am stuck on making a matching sprocket. You can see from the photo that it goes. 2 Holes, 3 Holes, 2 Holes.... This is a funky hard to make sprocket. For now its a laser man bracelet.
