Adventures in Minox Scanning

I do like working in OPENSCAD

I’ve been investigating the scanning of Minox films. These films are a mere 9mm or so wide and the negatives are teeny tiny. I’ve been wondering if the distance of the negative from the scanner affects quality. To test the theory I made the film holder above. Each holder is a different distance from the scanner base. I’m 3D printing the holder, so I’ve made each one print layer (0.2mm) different from the other. I got the original height by measuring a PENSO holder I already had. It will be interesting to see if the different negative heights make a difference.
