My first attempt at an old style radial aircraft engine. It's bit of a mashup with aspects pulled from the famous La Rhone engine and others. Print this pretty large as some components are quite small and need the size in order to not snap off.
I printed this on a replicator 2x and it functioned well. Make sure you set it up with scaffolds and a raft. Also, make sure it's scaled fairly large as some of the smaller pieces are quite delicate. Keep an xacto handy for cleanup. There will be a bit to do!
All in all, I'm pretty happy with this one. Now to make it hollow and functional!
