Crankshaft - Vilebrequin - Cigüeñal

Original design comes from http://koi29.info/solidworksF-vilebrequin.html It's a tution for solidworks. Part is for a Nissan 2.2 D
I found several stl files on grabcad

I designed the stand to look good on a desk but mainly to show to my students that all the central cylinders are contributing to the same rotating pair.
Therefore they must be toleranced as a whole so it is a good an easy way to understand example of common zone tolerancing

In dec'17 I changed the file for the stand as I have redesigned the cylindres for them to lock around the crankshaft better

Enjoy
