Pneumatic Radial 6 Cylinder Engine

thingiverse

(In progress, shooting for early 2019 update) This model was part of a student modeling project for AutoDesk to beta test Fusion 360. I finally got around to 3D printing it and uploading the parts. This model does not have the best tolerances for 3D printing so there will be some sanding needed on the piston/cylinder assembly and the pins. (Could also be due to using ABS for those parts) Also, for assembly, hardware will need to be force threaded into the plastic, so be aware of this to avoid splitting your parts!!! Below is a B.O.M if you would like to print this. <ul> <li>Base_Stand X 1 (optional)</li> <li>Bearing_Holder X 1 (optional)</li> <li>Rear_Bearing_Stand X 1 (optional)</li> <li>Connecting_Rod X 6</li> <li>Connecting_Rod_Hub X 1</li> <li>Crank_Case X 1</li> <li>Crank_Case_Cover X 1</li> <li>Crank_Case_Gasket X 1</li> <li>Crank_Shaft X 1</li> <li>Crank_Shaft_Counterweight X 2</li> <li>Crank_Shaft_Pin X 1</li> <li>Cylinder X 6</li> <li>Cylinder_Head X 6</li> <li>Cylinder_Head_Gasket X 6</li> <li>Flywheel X 1 (optional)</li> <li>Piston X 6</li> <li>Valve X 1</li> <li>Valve_Crank X 1</li> <li>Valve_Housing X 1</li> <li>h8X16_Pin X 6</li> <li>h8X20_Pin X 4</li> <li>h8X30_Pin X 6</li> </ul> You will also need hardware for complete assembly. The hardware includes: Bearings X 2 Ball Bearing for 12 mm Shaft Diameter, 28 mm OD Cylinder Fasteners X 24 (1/4-20 X 3 in) (I couldn't find a cheap M6 at this length) Crank Case Cover Fasteners X 6 (M6-1 X 10mm) Valve Cover Fastener X 6 (M6-1 X 30mm)
