Canon 8-15mm Zoom Gear for Nexus Underwater Housing

*** Canon 8-15mm Zoom Gear for Nexus Underwater Housing ***

I created this ring gear for the Canon 8-15mm Fish Eye zoom lens.
The ring gear engages with the zoom control gear inside the Nexus 5DMkII underwater housing.

2.62mm O.D. o-ring material is used to create the lens body friction surface.

Suggested printing is at 0.1mm resolution with 100% fill density for strength.
