Last night, I spent 3 hours putting this together in Solidworks from scratch. The tutorial I found for it was fairly ambiguous, so I had to rely on my wits to get a lot of it correct. After finishing the main body, I spent another hour making the proper proportioned chain-links and keychain. After I finally finished assembling it, I changed up the colors for Kingdom Key D.
