Are you heading to a dark and gloomy place ? This easy to print (no supports required) 3D Print will allow you to use a 12V / 60W Equivalent LED Light bulb (2 packs are around $8 on amazon). A 4AH battery should run a bulb for about 10 hours. A great thing to have around to light things up in a power outage, under your car / crawl space / etc … Uses roughly 18g of filament, prints in roughly 40 minutes on 100% speed.

Positive Terminal Instructions : Cut a roughly 100mm long strip, feed it up inside the left most hole from the ryobi terminal interior side of the adapter (left most with circle facing upward), feed through some excess and bend into a U shape to feed the strip into the hole next to it (the one off center right). Needle nose plyers or tweezers may help with this. Once the nickel strip is fed back into the return hole, bend over as seen in the photos. Then work backwards to remove any slack, then cut the left over strip slightly past the bottom, again forming a U shape and feed the strip into the securing portion that would supply to the posititve ryobi terminal.

Negative Terminal Instructions: Cut a roughly 50m long strip, feed it from the battery port adapter side in the ‘side hole’, repeat the U forming into the battery terminal negative side. NOTE: This side doesn't ‘lock in place’ so some glue would be suggested after seating this strip to hold it in place (you should be able to drop some glue in the U-hook where the battery terminal links on).

Additional Notes: This is designed to be a fairly tight friction fit. Depending on your printer you may need to print the model at 101-103%. Though printing at 100 on my P1P works just fine. I used 10mm nickel stripping myself and cut it down to size as needed as I wanted a reasonably wide, but I'm sure 6mm / 8mm would also work fine.
