50mm lens holder

thingiverse

A 50mm lens holder with a semicircular slot, 3mm wide, is designed to hold lenses during demos and optical experiments. Adjustable SCAD file allows customization of dimensions. A "50mm Optical Glass Lens Collimator Plano-Convex for Led Projector" fits this holder. Printing issues may require a raft or adjustments to settings. Alternatively, a hand-carved polymer clay version can be made without a printer, albeit with a less polished appearance and increased effort. A similar 75mm lens holder is also available on Thingiverse, while a 50mm lens holder that fits on a yardstick can be found there too. Extra Information: - The printable 3D item is functional but may require a raft or adjustment in settings to prevent cracking off the bed during printing. - A handmade polymer clay version is possible, but it requires more work and doesn't look as polished as the printed one. - Other lens holder designs for different lens sizes are available on Thingiverse.
