Flashlight to use at telescope

thingiverse

This is a compact flashlight designed specifically for use with a telescope. It relies on two bright red LEDs that provide clear visibility even in low-light conditions. To assemble this flashlight, you will need several key components: four M3x20 bolts, one M3x6 bolt (choose the smallest head available), two red LEDs, one miniature switch, a small spring for the negative terminal, and a single 18650 battery. To secure the diodes and switch in place, hot glue can be effectively used.
