Sprocket Mask for lef__rsa JJC film scanning adapter

The original design lets light pass through the sprocket holes and bounce around the enclosure creating heavy vignetting. I've made this to counter the vignetting using the STL file and working around it.

Painted with matte black paint for optimal performance. This doesn't let me run film through if the tip is shaped like __/, so you must cut it so it's flat and it slides right through (or just wiggle it a lot).

There's still a bit of vignetting but it's much more manageable with the vignette correction in Lightroom.
