I needed to repair a T66 flashlight that was missing its lens. This lens retainer will let you use a generic 28mm acrylic lens from AliExpress. Simply insert the lens between the 3D printed part and the flashlight and screw in place.

Recommendations:
- Material - Any. Clear filament also turns the head into a small diffuser.
- Layer Height: 0.16mm
- Brim: Outer and Inner, 3mm
- Wall loops: Max (You want the whole print to be wall loops)
- Top / Bottom surface pattern: Concentric
- Infill - N/A, your wall loops should create a solid print.
- Orientation: Print with screw threads on top.
- Supports: None
