Our AR Sandbox prototype, as shown on my web site, fits tightly through a standard door, with the projector/camera arm removed.

Whenever you remove/reattach the projector/camera arm, you have to re-aim the projector and camera (unless you have a mechanical means to ensure that both end up exactly the same as before), and re-run the full calibration procedure (4: measuring base plane, 5: measuring box extents, 7: projector calibration). With a bit of practice you can probably do that in five minutes, but it needs to be done.

We currently recommend the BenQ MX620 short-throw projector. Street price is around $530.
