Working V8 Engine - Easy 3D printable

thingiverse

Here is a link to my 3D model that's derived from the GrabCAD V8 engine desk toy: https://youtu.be/vWFyRtlEq_g This design incorporates several changes. I've modified the pistons so their gudgeon pins span the entire width, upgraded the connecting rods with a snap fit system, streamlined the crankshaft into a single piece, and added a handle to manually turn the engine over. To assemble this model, follow these steps: 1) Simply print the individual components: EngineBlock.stl (1 piece) CrankShaft.stl (1 piece; recommended print orientation with support using Simplify3D) 2) Drill four holes into the Engine block for securing the 'CrankshaftClamp'. 3) Snap 'PistonArm's to the Piston heads. 4) Snap 'PistonArm's to the crankshaft, ensuring the hook remains hidden. 5) Tap the end of the Crankshaft with an M4x0.7mm screwdriver tip. 6) Use three M4 flat washers as spacers between the Crankshaft end and Handle. 7) Secure the handle to the crank shaft using a 10mm long M4x0.7mm socket cap screw. 8) Insert the assembled crankshaft into the Engine block. 9) Screw on the clamps with self-tapping screws. 10) (Optional) Apply silicone-based oil to lubricate cylinder walls, piston wrist, and crankshaft bearing surfaces. 11) Manually turn the handle or use an electric screwdriver for optimal performance.
