thingiverse
A 4-cylinder engine's flat crankshaft design is paired with the given piston/rod setup: http://www.thingiverse.com/thing:100282. The custom counterweights, main journal, and hexagonal flywheel head facilitate easy cranking. Printing both halves simultaneously or separately reduces print time for optimal results. My PLA printing settings: Layer Height 0.5009; Honeycomb fill at 0.25.
