During a power outage a few months ago, I realized that the mini white flashlights that I had had one flaw – they ruined my night vision. Here is my solution to that problem: a dual color mini flashlight.

With a red LED and a white LED, you can preserve your night vision for midnight bathroom treks (useful for camping and power outages) while still having a white light handy. Or you can use two LEDs of the same color for more light. (Or you can rock two random colors for a ceiling light show)

Materials: Two LEDs and a coin cell battery (CR2032).

Printing:

• PLA, although any should work
• Any infill
• 0.1mm layer height, although 0.2 should also work

Assembly:

• On each LED, bend both pins outward and then inward so that the distance between the pins is roughly 5 mm and they are parallel.
• Then bend the positive (longer) pin inward a little bit so that the end is less than 3mm from the other pin.
• It should look like:

• Now slide the switch onto the positive pin, and slide it onto the battery. Make sure the positve pin is on the positive side of the battery.
• With both done, it should look like:

• Place the battery and LEDs in the the base with the switches pointing upwards.
• Stick the cover on top.
• Clip on both clips.
