ev200d diopter frame

thingiverse

Customized frames for bigger DIY lenses, perfect for those who need assistance due to vision issues and can repurpose spare lenses from glasses. Print between 0.1 - 0.24 mm thick. To protect the lens during grinding, use painter's tape. Grind the lens with 80 - 120 grit paper and gradually increase to 240 - 300 grit as needed. First versions without teeth require hot glue or non-invasive adhesives for attaching the lens since most lenses are made from resin or acrylic. Always test on a small piece of lens before gluing. Please provide feedback, and if modifications are required, ask. Lens measurements are: 23mm / 16.7mm / 3mm (for 9). For best results, use the holder as a template, cover the lens with electrical tape, draw the shape, and then start filing until the drawn line remains visible. Update: Added slimmed versions for smaller diopters. March 15, 2019, added further two improved slim versions with teeth to hold the lens in place.
