I've revised the 3D design of my 6 tooth super 8 film sprocket wheel slightly, and had a pair of these new ones printed at Shapeways.com
I reduced the size of the sprocket teeth this time and ordered 'fine detail white plastic'. Here's the result, and this time, the teeth do seem to mesh with a piece of film. Encouraged by this, I've just sent away my design for a 20 tooth sprocket...

Hi,
I am in the process of doing the exact same thing.
If possible, could you share your cad files with me ?
(I gather from the 20 teeth, you will be using a 1.8deg stepper motor, and this lines the frames up perfectly...)

Very cool blog! Hi, would you mind sharing the 3d files for the sprocket? I wanna build a transport mechanism for scanning film with flatbed scanner and it would be very handy to have these sprockets. Many thanks!

Hi there Narigas and Jacques. In my final design that I have used now to capture a couple of super8 films, I settled on a 20 tooth film sprocket (see later posts).
I've made the sprockets available on the Shapeways website, so they can be ordered from there...

Do you mind making a standard 8mm version of this sprocket with 6 teeth?
