Excellent work! I've been looking for a easy diffuser for a 3 mode flash light I use as for a bike light. I use the full power mode for lighting the way in the morning but I wanted to be able to use the strobe mode during the day just to get the attention of vehicles but it's just way too bright I think this could solve the problem!

Spectacular. I've been looking for a simple diffuser for my LED flashlight to hang in my tent. I'm going to make one of these right now! Thanks.

Cool thanks, let me know how it works out for you.

I prototyped mine with paper rather than plastic. It worked well - but maybe too well. The light is fully diffused. I'm thinking plastic will allow me to still "flood" the light in a general direction.

Instead of making a round end-cap, I pinched the end and taped it. That approach has some pros and cons.

Yah my prototype was just wrapped around and then kinda pinched together. Still works but I prefer the round cap because I leave my cap on my stylus pro all the time and the round cap fits it flush.

I noticed that from your video. That's definitely the "pro" of making a proper end-cap.
