Anyone ever stack in your 3D printer?

I am attempting to get the most out of my printer by stacking the prints. Has anyone ever done this? My printer is large, but I still need to tilt these full size long-bed truck frames to get them on the bed. 

Have you tried it and if so, what was the results? Here is my plan:

Interesting setup!

I've never tried it but it certainly could work.

One thing I would caution on is the fact that you are multiplying the load on the lowest layer of supports, especially the first ones that print. I would make them medium diameter.

That of course may make them harder to remove, or clean up.

There is a script or program someone made to add floors for doing this, I think Joel Telling did a video on it.
