I was curious, and decided to stack all the various bits of extension
tubes and whatnot I had together to see what I could get. Equipment used
for these shots:
E-330 -> OM bellows -> OM auto extension tube-> 7+14+25mm manual
extension tubes -> Miranda 28/2.8 lens; E-330 on-body flash used to
trigger an FL-50 on an optical slave, and a bunch of manual fiddling to
get exposure right.
Subject: a Leatherman micra, the 1mm scale edge. These are uncropped;
this is the full image, just scaled for web consumption.

The distance between the two notches is 1mm, so total distance across
the image is probably ~1.3mm. Working distance is probably somewhere
around .1mm. That's why I'm using the Miranda lens -- it's thin enough
that I the subject didn't need to be inside the front element, and also
if I'm going to be pressing metal against the front element of a lens,
I'd rather it wasn't a lens I cared about too much.
Yes, technically, these leave something to be desired -- I should
probably have used a third hand or something to hold the subject in
place; the depth of field is insanely small, and this lens isn't really
meant to be used close up. However, I was surprised I got anything at
all, to be honest..
Now, I'm sure someone out there on the list must have two sets of
bellows, at which point you could use a 65-116 tube to join them
together (possibly even just manual tubes, I'm not sure how much you'd
need to stretch). And I forgot all about reversing the lens until just
now, too.
Also, theoretically, you could try gutting a 2x converter and sticking
the ends on a long bit of black PVC pipe, but I think making sure
everything lined up properly would be a big pain there.
