I designed and built a 3D Printed Compressed Air Engine and wanted to share the process I went through designing this, including some of the mistakes I made!

All of the parts were printed in PLA using 0.4mm Nozzle. Layer height varied between 0.12mm and 0.20mm depending on the size of the part (smaller parts have smaller layer height for more precision).
