This inline 4 cylinder engine block is designed to use with my rotating assembly parts. I cut away part of the front of the block to allow for easy viewing of the internals in motion.

The color picture is of the whole lower end minus the hand crank adapter, but this thing is just the block and stand. Get the rest of the parts here:

Engine Crankshaft:

Piston and Rod with bolts, nuts, and pins included:

Hand crank for the crankshaft:

I have all the parts translated into position in the scad files but commented out to allow for playing with the fitment but it should all line up with minimal gaps to allow for freely moving parts right out of the box.

If the tolerance is too tight, a nice acetone bath for the pistons and crank should grease things right up!


The block prints deck-first (vertical but upside down) and prints 102mm tall, but it's not very wide/long. I have an 8x8 bed and I don't even use the whole thing yet I still have no problem printing everything. The biggest print is the crank.

great item. Just a note: how do you plan to get the crank in the block? I printed this and had to cut the bottom to fit the crank. Maby you should change the design ? ;)

Did you print the stand? It's supposed to be a cut-away of the block and you'll need to put the block in the stands to make it fit. The multicolor image seen here is with each piece put together in openscad. What you see there is how it should be when you print it. The only problem I had was I didn't really leave any room for tolerance. So you might want to scale up the block 3-5% just so everything can move. I had to shave the lip off my rods to make them fit in the crank.
