Here's another good one!! They just posted a wrench that they printed in space..  http://nasa3d.arc.nasa.gov/

Would be interesting to see it printed I think it was designed to be printed on 2 nozzle technology, or SLS also very tight tolerances around 0.1 on some movable parts.

Interesting to see that the STL is  a Stratasys mesh, which means it was written by a Stratasys software.

Only the best for NASA.. lol I think they should have made the 3/8 shaft separate. Have it slide into a square hole on the ratchet wheel. Much stronger..

I think they printed on one side with dissolvable support or SLS.

Their supposed to have a T-Rex scanned soon ☺

I found this website that lists 3d Download sites (25 in all from different countries as well)

http://www.hongkiat.com/blog/download-free-stl-3d-models/

and Defcad.com doesn’t work anymore.

I'm told, and have no reason to doubt, that at least some of McMaster-Carr's 3D models have errors that may make them unsuited for exacting, direct use. One example would be fastener threads, which don't seem to be in accurate thread formats.

3D Content Central is also another site with lots of 3D models:

though most of them are probably not really suited for 3D printing.

You are correct, the models that McMaster Carr provide tend to be broken for some reason. I use them as place holders in a model however it is not optimal, Ill ask around and see if they can be repaired.

Wow. Thanks. I've been looking for bolts and that and Mcmaster is perfect for what I need.

A good 3D CAD package can created perfect thread forms.  I use GeoMagic Design and that works quite well.  DesignSpark is free and may also be capable of making real threads.  GrabCAD may also be a source of downloadable fastener models.  You could also try Thomas Register - http://cad.thomasnet.com/cadmodels.html
