Just finished printing this Ford Model T engine and trans. The original stl files came from a fellow named Chuck Ridley on Grabcad. I started printing some of the parts then realized there were errors in the part modeling so I set about correcting everything from online information about the model T. After about 60 hours of redrawing, massaging and creating completely new parts I have what I think is a quite accurate 3D printed model T engine. Two of the parts, the oil pan and stand were too big for my Ender 3 Neo so I split them into two pieces and super glued them together. Being that I'm also a machinist I made shafts and pieces for parts that would be too small to be printed with any strength. The original stl files are drawn full size and this model is one quarter scale.
A few of the things that were completely remodeled were the block, the exhaust manifold, the carb heater baffle, the fan and bracket, the timing cover, the ignition timer, the 'Hogshead' or transmission housing, the head and various other small parts.
