Here's a simple solution to spreading out the beam of a small flashlight. There are three sizes: To fit a standard Mini-Mag flashlight (2AA), an El Cheapo aluminum 3AAA (Harbor Freight and others) LED light, and a 1AA pocket LED flashlight (Ray-O-Vac, I think). Fits perfectly (snug) on the light. Great as a camping tent light or area light. Print in white for lots of diffusion, clear for less. Print in red for an instant astronomy/night vision flashlight!) Edit: Added one for a 1AAA light (SkyWolfEye 3500LM) Edit 01/20/2019: Added cone diffuser for 2AA Mini-Mag light. Now you can play traffic director!
