This is derived from the grabcab model:

I changed the pistons so their gudgeon pins are the full width, the connecting rods are now hook snap fit, the crankshaft is one piece, and added a handle to crank the engine over.

1) Just print:
nEngineBlock.stl 1pc
nCrankShaft.stl 1pc (Print the crankshaft on its end with support. Simplify3D recommended)
nPistonArm.stl 8pcs
nPistonHead.stl 8pcs
nHandle 1pc
nCrankshaftClamp 2pcs

2)Drill 4 holes in Engine block for securing the 'Crankshaftclamp'
n3)snap 'PistonArm's to the piston heads
n4)snap 'PistonArm's to the crankshaft (make sure the hook is hidden)
n5)tap the end of the crankshaft M4x0.7mm
n6)use 3x M4 flat washers as spacers between the crankshaft end and the handle
n7)secure the handle to the crank shaft with an 10mm long M4x0.7mm socket cap screw
n8)drop the assembled crankshaft into the engine block
n9)Screw on the clamps with self tapping screws
n10)(optional) using silicone based oil -> lubricate the cylinder walls, piston wrist, and crankshaft bearing surfaces
n11) turn the handle manually or use an electric screwdriver for the best effect.
