This is a 50% scaled-down model of a model boxer engine that I designed awhile back:

Each piece can be printed without support.

Snap together and turn the crank. There's also a handy knob to help it turn without wearing out your fingers.

Here's a friendly video of it in action:

If you found this useful, it would bring me great joy to see your work - so be sure to share; especially if you print the casing in transparent filament! :)

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:
