Flashlight Diffuser (adjustable)

thingiverse

This is a versatile and customizable diffuser for LED flashlights. It's useful when the flashlight has too narrow a beam and you need wider or softer light. The flashlight with this diffuser can be hung from a tree branch or from the top of a tent to illuminate a larger area. The default dimensions are set up for the Zhishunjia ZSJ-T29 flashlight available at DX.com: http://www.dx.com/p/zhishunjia-zsj-t29-cree-xm-l-t6-1000lm-5-mode-white-flashlight-black-1-x-18650-317226. However, I wouldn't personally recommend this flashlight due to its stated 2.4A circuitry and 1000 lumens, but in reality it delivers only about 600 mA to the LED, equivalent to approximately 250 lumens for a Cree XM-L T6. Check out my other diffuser for the LZZ-186 headlamp, which is slightly more complex: http://www.thingiverse.com/thing:187055. **Printing Instructions** To print this design, use a white material naturally! The best method is to download the OpenSCAD source and adjust the parameters near the top of the file according to your needs. The provided .stl file is designed specifically for the ZSJ-T29 flashlight. The key parameter to modify is ring_d - the diameter of the flashlight head. Add a little extra space around it, which I added 1.0 mm. Then, set clip_h - the height of the clips above the print platform based on where your flashlight has a narrower place for the clips to attach. The diaphragm parameter determines the thickness of the diaphragm - thicker means less light is transmitted, and thinner may not be very sturdy. I used 0.5 mm, which equates to exactly two print layers since I use 0.25mm layer height. Leave other parameters intact unless absolutely necessary.
