16mm Sprocketed Roller

Download Example STL

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 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 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 and contact_printer projects on this site.

Usage

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.
