I shoot a lot of MF3D (Medium Format 3D (stereo)). Mostly I use a
Sputnik, but I started with twinned Lubitel 166 Universals (not the
recent Lubitel 166+), and various MF cameras on a slide bar.
Do you have the Holga 120 3D Stereo Pinhole Camera? It's probably OK
as Holgas go. I've also shot MF3D pinhole with a Zero Image camera,
and with a 4x5 pinhole camera. You want to make sure that there are
no light leaks. You will probably also have to flock the inside of
the camera to make sure there is no internal flare. The Sputnik also
has these problems (and others) until you tune it.
The Holga viewer and slide mounts are junk. The mounts have the wrong
spacing to be easily viewable, and the viewer is very low quality.
I brought a few of my slides and a viewer (made by a friend in Canada
and no longer available) to the 2010 Photo Plus Expo. The Holga
samples (lens and pinhole) at one of the booths weren't too bad in a
good viewer, but my own views (taken with a tuned Sputnik) looked
awful in the Holga viewer.
3D World in China is currently manufacturing 120 film stereo cameras
(the TL-120), plastic mounts, and viewers. The cameras are OK, but
expensive. I don't like the plastic mounts, but I'm a traditionalist,
and I want the cropping that is available with cardboard mounts (6x6,
6x4.5 portrait, 6x4.5 landscape, and panorama), which are no longer
widely available. The viewers are good. They are not as good as the
previously available hand made viewers, but they are readily
available, and much less expensive.
If you'd like more stereo information you can look up the photo-3d
(general stereo photography) and MF3D-group (specializing in Medium
Format stereo) mailing lists on yahoogroups, or some of my earlier
ramblings about MF3D on this list.

Some MF3D folks use Dr5 to produce B&W stereo transparencies. They
can look nice, but are expensive. Tech Pan in 120 was the best B&W
transparency film (much better than Scala), and some folks on MF3D
were reversal processing it at home, but Tech Pan hasn't been
available in a long time.
