Engineer 3D Prints Entire Working Engine -- A Locomotive is Next

[matterest]

Hi Matt,

The cylinder block was printed in one piece (not counting the caps). I attached a zip of the files. Sorry it is so disorganized. I designed it in FreeCAD, so you can open the design file in that to see the assembly. The aluminum rod used for the crank shaft and vertical supports is 1/4", available at any hardware store. I believe the screws for the caps were 4-40 and the rest were 6-32. I'll be happy to answer any questions you have.

thanks for uploading the files! now i just hope my printer is big enough.
