Anna-40-6 glow gasket

thingiverse

This gasket is designed specifically for printing in glow-in-the-dark (GID) filament and sits perfectly behind a LEDiL Anna-40-6 lens/optic. I used this design in my custom build Convoy C8 flashlight, but other hosts may require modification due to its simplicity. There are four versions available: thick and thin designs for both the Anna-40-6 and Anna-40-7 lenses. Some filaments work better when printed thicker. After purchasing a Turbo Glow gasket for one of my triple 20mm optic flashlights, I searched for one that fit my Convoy C8 conversion (parts sourced from LED4Power). Unfortunately, I couldn't find one. Most Turbo Glow sellers specified no 3D printing, so I decided to try creating one myself. Glow-in-the-dark (GID) 3D filaments have some drawbacks. The first batch I bought from Amazon by AngeliteCare was subpar, glowing only under a black light. However, the second batch I purchased from SunTop on Amazon performed much better. Still, GID filament is abrasive and can wear out your nozzle quickly. To mitigate this issue, I've ordered a hybrid brass/stainless nozzle. Other options for creating a gasket include printing with normal filament and applying GID tape over it. This requires carefully cutting out the holes to ensure proper fit. I experimented with using the 3D printed gasket as a mould to cast clear UV epoxy resin infused with Strontium Aluminate. While the SunTop filament was good, the Strontium Aluminate produced an even better result.
