127 Roll Film Clip
This is a trivial remix of Larry's 120 Film Clip (https://www.thingiverse.com/thing:952014). It is simply that design scaled down to fit 127-format film.
This clip can be printed on an FDM/FFF printer without supports; although the upper bars are likely to droop a bit, the design will work. Add supports if you like (I didn't). I've found that a rather wide brim is necessary for bed adhesion, but it's possible you'll have better luck without a brim.
I've tested this on both genuine store-bought 127 film (as pictured in the photo) and on extra-long 127 rolls re-spooled from 120 film. The latter rolls are wider in diameter, but the clip is sized to work with either type of film.
