Ural keychain (IMZ) - Irbit Motorcycle Factory (no frame)

I happen to own an ural sidecar motorcycle. There is a huge set of keys coming with it, so I've decided to make several keychains to get them sorted out. As far as I am aware this design might also be handy for the U.S. as well as many people own urals there. I've made three different designs and recommend to print it using 100% infill.
