thingiverse

The LED Tardis charm features a built-in battery holder that takes two AG6 batteries and is designed for 3mm or 5mm LEDs. A hole is also provided for 6mm jump ring or earring attachments. You can purchase this charming accessory from Etsy if you don't have a 3D printer. The latest design of this charm has improved battery holding without cracking and allows easy replacement of batteries. To assemble, first print the battery holder and LED top according to your preference. Place two AG6 batteries in the holder, ensuring they face the same way. Slide the LED legs into the slots in the battery holder, aligning the positive leg with the positive face of the battery. Feed the legs through the bottom's holes and fold them over into the provided channels on the base. Use superglue for added stability. Scrape any excess material inside the top near the opening. Lastly, slide the battery holder into the top section, ensuring it aligns with the grooves in the top. No soldering is required; friction will hold the bottom in place.
