Yes. I ended up making one with parts and 3D printing. But there are plenty to buy.

Mine is build as follows: 1. I’m using threaded hoods to attach to my lens and create a cylinder extending out. 2. I have a second piece which slides over the end of the tube with a bit of movement closer/further from the sensor to fiddle with focus and magnification. 3. The piece that fits over the tube has a piece to hold the film and show only one exposure at a time. Behind the film is a diffuser and a light source.
