Designing a 3D Printed Scanning System for Cut Strip Negatives – By Stuart Jenkins

I’ve designed and 3D printed some film holders that work well with cut strips, and the models are free to download on Thingiverse.

The negatives need to be held flat, but many people report getting ‘Newton’s rings’ interference patterns when they’re just weighted down directly onto a lightbox. Then there’s the light source itself — it’s hard to get a completely even area of pure white light.
