If anyones interested, Here's the 3D object to print from. It's not been tested though as I don't have a 3D printer so may need modifying. I designed it so the image area of the film isn't touching the sprocket.

I can understand that the flat surfaces between the sprockets would protect the film surface/ emulsion, but why the irregular outer rims? This would only serve to damage fragile or brittle film. Surely a simple circular shape would be better. All film sprockets have that feature.

Thats just the way SketchUp renders circles to save processing power. It'll be perfect circle when printed. Ill do a proper render as the image was just a screenshot of one of the views in SketchUp.

Good job, Billy ! I was wondering, as Maurice, what you would do with it. Do you have a specific project or were you asked by someone else to manufacture those sprockets ?

Its just for personal DIY projects.
I built a telecine using the Bingoscope projector and thought I might need a sprocket to stabilise the film but it seems ok without it.
So decided to make my own version of the Film-o-Clean (as its so expensive!) using some good ol Lego Technics! It will have interchangeable sprockets and 9.5mm is one of them. The sprocket will go onto the top right spindle. If I ever get to 3D print it that is!
