[ExI] 3 d printer with moving parts

If the model leaves enough space between the parts, then you can blow
out the powder between the moving parts once you are done printing. I
think they skipped the step where they modified the cad to make the
hidden parts of the wrench work. Notice on the big gear thingy, that
the movement is a little loose. I would suspect that it would be
possible to get spaces about the size of a human hair, but the smaller
you go, the harder it would be to get the non-bound powder out.

I wouldn't want to depend on that wrench to get me down from space...
:-) He didn't torque it very hard the way I was looking at it.
Nevertheless, very cool indeed. Now, if it could just print a brain...
:-)
