Film Reel

When working with 4mm wood, I craft a 9.5mm reel that can be customized according to your film and material specifications. A recommended formula for determining the ideal reel width is (material height) + (film width) + (1mm). This formula ensures optimal functionality, especially when using different materials. For added convenience, it's useful to edit holes if needed. You can find more information on this design at http://www.thingiverse.com/thing:41999.
