s12 Flashlight Modification: Illuminated Ear Pick (for Near-Infrared Experiments)

If you also face the situation in psychology/neuroscience research, where subjects' hair blocks the light source causing poor signals during near-infrared brain imaging experiments, you can try using an illuminated ear pick to part the hair and solve the problem. However, truly good illuminated ear picks are rare, and most of those delivered by takeout are too disposable. So, I conveniently modified my s12 flashlight into an illuminated ear pick, without affecting the side light and charging.

· Modified using an S12 flashlight

· Only 2 pieces of 2*8 countersunk pins are needed for fixing

· The side light board is recommended to be printed with transparent filament, the print profile is already configured, and it is recommended to print with a frosted PEI plate to achieve more uniform light

· The ear pick head can use disposable tips

· A1 mini can print
