Tiny
This little engine is another of Elmer Verburg's designs. It IS tiny and it's name implies.
The parts were all made in one day. Small but not terribly difficult to make.
It went together pretty easily. The only adjustment I had to make was to turn the back end of the piston a little shorter to clear the crank. Everything else was fine to print.
The finished engine looks like this, next to a dime for scale.
