<p>I made a Minox film holder to work with the 35mm slide adapter on my Nikon CoolScan. I found the main challenge was holding the film sufficiently flat without damaging it. In then end I used some very tiny magnets to clamp the two parts together.<br>
I made the design public on Shapeways in case anyone else found it useful. I don't know whether it would work with the 35mm slide carrier on other makes of scanner but am guessing something similar would.<br>
