# Film Cores
|
|
|
|
|
|
|
|
Film cores are used wind film for storage, handling, editing or projection.
|
|
This project contains a script for generating cores of arbitrary diameter, and the standards of 2 inch cores for camera usage and 3 inch cores for projection are included as printable STL files.
|
|
|
|
This script will generate cores for 16mm, 8mm or 35mm gauge films.
|
|
These can be used with the [split_reel](../split_reel) module.
|
|
|
|
8mm cores are not common or standard but these seem to work.
|
|
|
|
This script will generate film cores with or without a center partition making them possible to print with no overhangs or support.
|
|
Keep in that *without* that center partition this makes for a weaker core and it may buckle under the tension of longer films depending on how it is printed.
|
|
|
|
Download the source and create an OpenSCAD file in the directory to generate arbitrary size cores as follows.
|
|
|
|
```scad
|
|
use <scad/film_core.scad>;
|
|
|
|
film_core(16, 4 * 25.4, true);
|
|
```
|
|
|
|
This will generate a 4 inch core for 16mm gauge film with a center partition.
|
|
|
|
```scad
|
|
use <scad/film_core.scad>;
|
|
|
|
film_core(8, 2.5 * 25.4, true);
|
|
```
|
|
|
|
This will generate a 2.5 inch core for 8mm gauge film without a center partition.
|
|
|
|
The script can even be used to generate cores for more uncommon gauges, such as Pathé 9.5mm.
|
|
|
|
```scad
|
|
use <scad/film_core.scad>;
|
|
|
|
film_core(9.5, 3 * 25.4, true);
|
|
```
