Boating Stuff - Nightlight

To some of you, this may look like it was intended for another purpose :-) but it's supposed to be a simple hanging nightlight. It's a red colored lens for the ubiquitous cheap led flashlight that sells for about $1. I wanted to make a red nightlight to hang in our boat to preserve night vision. This might be nice for camping too.

I'll upload a slightly larger one soon, if you print this, I'd scale it to fit your flashlight. I had to sand this first print on the inside edge a little bit to get it to fit.

I bought clear red filament but I think this might work using clear filament with a bit of red magic marker applied to the filament. I think I'll try that soon, if you do, let me know if it works! Here is a marker holder design for filament
