This handy tool acts as a shield for the sensitive optics found inside projectors by providing a barrier against harsh chemicals contained within corrosive resin. The creation process involves molding tiny metallic tubes called cylinders using 3D printing technology, allowing for precise dimensions and complex geometries to be achieved efficiently. To assemble this protective mechanism, one merely needs to install it near the area that requires safeguarding and then compress one of its components into a secure, irreversible state using heat applied directly onto metal.
