I needed a reusable way to attach a coin-cell battery to a single 3v LED as well as something I could hand to just about anyone without any explanation and they could figure things out just by looking at it.
Just enough of the battery sticks out where you can remove the battery and put in a new one.
One battery will last you for days, maybe even a week.
I use these to add markers to movie and commercial sets for visual effects, but these are great for decorations or anything that needs a wireless LED light attached.
Prints quick at 15min for 1, or about 2 hours for a batch of 20.
No supports needed.
Pro-tip would be to mark the positive lead on the LED with a sharpie, or something, so it's obvious which is which after feeding them through.
No tape or adhesives needed, just feed the leads through the top (positive on the + side and negative on the - side) and then bend them outward and back up and they're secure.
I like to bend the LEDs at 90° towards the negative side, but you can just feed them straight in, if you prefer. (bending them that way gives me a flat side to tape to a wall, add a magnet, or add some velcro)
