This is an adapter mount for scanning 126 film (Instamatic) on an Epson Perfection V550, V600 or V700 flatbed transparency scanner. It fits neatly into the 6cm x 22cm medium format frame, keeping the film square and flat.
I’ve designed it to keep the film the same distance from the bed as the other frames to ensure correct focus. The two halves simply clamp together to keep the strip of film as flat as possible.
(Oh, and obviously print the top half top side down.)
