Advanced Diffuser for Noctigon DM1.12 Flashlight

A long-awaited update to my advanced diffuser projects, new especially for the Noctigon DM1.12 dual-channel flashlight!

This diffuser will turn the flood channel into a highly effective lantern, casting light down and out the sides much more than any other diffuser available today! Not only that, but it leaves the center throw channel completely unblocked in order to maintain long distance usability! This also opens up the possibility of using tint-mix mode to provide local light with the lantern attachment, and whole-room illumination using ceiling-bounce with the throw channel.

Note about heat: There is always a concern about using soft plastics with high powered flashlights. I have tested my builds to the point of standard indoor thermal throttling with Emisar/Noctigon lights and experienced no issues with PLA diffusers. Nevertheless to that effect, I have taken care to incorporate design elements into this diffuser to allow ventilation to further decrease the risk of melting or warping the diffuser while in use at high power levels.

As with my other projects, this diffuser applies principles of diffraction, refraction, and reflection, in order to create the most efficient, advanced 3D printed diffuser available! In fact, in terms of ability to deflect light in outward directions, I'd put my diffusers up against any currently available for any flashlight!

Be sure to check out my other things for my other diffusers and flashlight accessories, including the same technology for Emisar D4/D4v2, D4S/D4Sv2, D18, and many more!

Print build notes:

Build with the wide/closed end on the bed, open end facing up. No support should be required. Infill should only be present in the thick spots, I usually set about 10% but have had success with no infill at all.

I recommend a 0.20mm layer height for a good mix of properties. Larger layers theoretically let more light through but how high of a layer you can make before you have problems is up to you and your hardware.

In general, the clearer and shinier the material, the better. Most "natural" PLAs work great, but I hear PETG works really well also! GITD is fun, and colored transparent filaments look really cool. Printing in white is also good if you want to emphasize low light/soft light.
