Fully Functional 4-Cylinder Crankshaft and Piston Mechanism

Hello everyone! This is a detailed 3D model of a 4-cylinder engine mechanism featuring a crankshaft, connecting rods, and pistons, designed in Autodesk Fusion 360.

It's a great mechanical assembly model for demonstration, educational purposes, or desk toys for engineering enthusiasts.

⚙️ Printing & Assembly Tips:

* Tolerances: Designed with 3D printing in mind, but please make sure your printer is well-calibrated for moving parts. Depending on your printer's accuracy, you may want to apply minor scaling if needed.

* Supports: May require supports depending on your orientation choices, especially for the crankshaft overhangs.

* Infill: Recommended 15% - 25% infill for a good balance of strength and print time.

If you print this, I would love to see your makes! Don't forget to share your results. Happy printing!
