Royal IR-100 Adapter

I recently got a Royal LetterMaster daisy wheel printer and couldn't find the IR-100 roller for it anymore. I modeled a base for it that I can use to carefully sticky tack on an IR-40 roller to the bottom. At some point I'd like something more permanent, but this gets the job done.

If you have a Royal Alpha 100 or Royal Beta 200 Typewriter, this is the adapter that you want as well.
