Toy Engine

Toy  motor:

This is an updated version of my original 2 stroke motor. Now all the tolerances are better and the exhaust port is not inline with the intake port. But the model is still just as fun as ever to print and play with! (This model is more meant as a toy than an accurate representation of a 2 stroke motor) 

Assembly instructions:

Insert the piston into the block. Then insert the crankshaft into the block with the long shaft down (the square on the end of it should come out the back of the block). Next attach the connecting rod onto the short shaft of the crankshaft. Then turn the crankshaft as needed until the connecting rod lines up with the piston and slide the pin through the piston and connecting rod. 

And that's it! Enjoy!
