Follow Your Focus
Free browser-based parametric generator that creates custom 3D-printable follow focus rings adapted to specific lenses for local fabrication
The product is a free browser-based parametric generator that creates custom 3D-printable follow focus rings adapted to specific lenses, addressing overpriced, proprietary and non-repairable filmmaking gear by enabling local fabrication. It is for filmmakers, hobbyists and independent creators who print their own camera accessories and want accessible, shareable equipment without subscriptions or accounts. Core generation runs locally in the browser with no cookies, using privacy-respecting aggregate analytics, and outputs STL files that can be used commercially with attribution.
