As Steve pointed out there is the Stack Shot rail. I bought a Kiwi rail
that works very well - mlocal camera store had on in sock:

One trick that I came up with was to put a small spring clamp on the
rail's small knob to allow greater leverage and fine control over the
movement of the rail. My old Pentax macro rail II sways a little as it
moves, which doe snot help the stacking process. It has a couple of
adjusting screws on it and if I ever figure out what they are I may see
if it can be adjusted to move without swaying. The Kiwin does not work
in the cold (gets very stiff) so I still use the Pentax rails for
snowflakes.
I think that Zerene Stacker may use 3D modelling internally with its
DMap process. I use a combination of the two methodologies available in
Zerene Stacker and also Photoshops stacking tool. I can't yet predict
which will work best for any given stack, and usually use all three
approaches. Lately I've been using PS to combine multiple outputs from
Zerene stacker with good results.

I was thinking about Mark's amazing macros and how much work they must be. I
know that there are setups to move your camera forward on a slide rail. Is
there also one that has a wheel with contacts so that every quarter turn of the
threaded rod clicks the shutter?
In a similar vein, does any of the stacking software construct 3d models of
the object?
