# 16mm Sprocketed Roller
|

|
||
|
|
|
||
|
|
This is a module for generating sprocketed rollers of arbitrary frame counts for 16mm-related gear.
|
||
|
|
It was originally created using the measurements from a JK optical printer gate and has been tested at different sizes.
|
||
|
|
|
||
|
|
[SLA printing](https://en.wikipedia.org/wiki/Stereolithography) has made it possible to print rollers with enough detail and precision to safely convey film for various applications.
|
||
|
|
An issue caused by [FDM printing](https://en.wikipedia.org/wiki/Fused_filament_fabrication) is that the larger z-layer height makes it nearly impossible to print the individual sprockets within suitable parameters.
|
||
|
|
|
||
|
|
This is currently being used in the [mcopy](https://sixteenmillimeter.com/projects/mcopy) and [contact_printer](https://sixteenmillimeter.com/projects/contact_printer) projects on this site.

|
## Usage
|
||
|
|
|
||
|
|
```scad
|
||
|
|
use <./scad/sprocketed_roller.scad>;
|
||
|
|
|
||
|
|
sprocketed_roller(sprockets = 12);
|
||
|
|
```
|
||
|
|
|
||
|
|
This will generate a sprocketed roller with 12 frames.
|
||
|
|
Other arguments will change other features of the roller.

## Reinforced 16mm Sprocketed Roller
|
||
|
|
|
||
|
|
This variation of the roller design allows the majority of it to be printed using filament and allows the sprockets to be printed seperately in a high-detail material like resin.
|
||
|
|
This goes with the `sprocketed_roller_reinforced_wheel` OpenSCAD module and by setting `reinforced = true` in the main module.

## Reinforced 16mm Sprocketed Wheel
|
||
|
|
|
||
|
|
This wheel should be generated along-side the `sprocketed_roller` module with the setting `reinforced = true`.
