Ender3NG Smooth Idler Upgrade (F695ZZ Replacement)

Remixed Ender3NG components adapted to support a mixed idler configuration using both toothed and smooth (toothless) GT2 pulleys, replacing the original F695ZZ-based setup. The geometry has been adjusted so the belt path maintains correct tracking and alignment within the CoreXY system depending on the pulley location.

Certain positions use toothed GT2 pulleys to maintain belt engagement, while others use smooth idlers where the belt runs on its back side. The parts modify the original interfaces to accommodate this configuration while preserving compatibility with the surrounding Ender3NG assembly.

The components are intended as drop-in replacements for the corresponding original parts, allowing the printer to operate with this mixed pulley configuration without structural changes to the frame.

Printed part photos and full assembly images will be uploaded as the build progresses.
