## Design Concept The concave lens frame is designed for customization on standard rails, allowing secure and precise placement of lenses in various setups. ## Function It is intended to hold concave lenses securely within scientific or prototyping environments, particularly useful in optical experiments or DIY projects. ## Printing Tips Use a high precision 3D printer with a minimum of 0.1mm layer resolution to ensure the exact fit needed for lens stability. A durable filament like PETG or ABS is recommended for strength. ## Assembly Instructions Ensure that the printed frame fits snugly onto your rail system. Insert the lens carefully without applying unnecessary force to avoid scratches or damage.
