This is a chain guide for the swing-arm of a Stealth Futr Alpha, however will likely also fit the Stealth Beta, Fighter and Bomber.
Does not require supports, or fancy print settings/filament. Just print with normal PLA.
In my case I have a 60T front chain ring (spaced out by a 38T and 52T) and the smallest rear cog is 14T. The guide is still effective on the 52T ring, but does nothing for the 38T. It's likely the design will need to be adjusted to suit what-ever chain ring sizes you run, but feel free to download and adjust to suit.
