Ringchaku Chain Remix

(CHAIN ONLY) You can buy the STL for full ringchaku from the link in license.Upgraded chain from the original ringchaku chains as the ori ones were very brittle even when printing with carbon filament. Hence I remixed 3D Printed Chain by Tony_D which is highly customisable in length, and not forgetting it so easy to assemble, with the end link not easy to break away from the ends.
