This is a model of a typical boxer engine like what you would find in a Volkswagen Beetle or Karmann Ghia.
Each piece can be printed without support.
Snap together and turn the crank.
If this model is too big for ya, I have a scaled down version posted here:

Here's a video of the smaller version in action:
If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
Or, better yet, please feel free to dump a bitcoin or two here (I'm trying to collect as many as I can before the apocalypse):

... include a note to the effect of "Hi 3E8, thanks for the boxer engine thing... my life is infinitely better on account of it and please accept this small handful of bitcoins in gratitude".
You're welcome! (in advance) :D
Also, feel free to peruse my other submissions which are almost as varied as they are many:
