Light Up House Keyring

thingiverse

This small home model can be built with a single coin cell battery and an LED cathode. Pressing the button activates the light within, revealing a miniature table and chairs inside. Feel free to add your own custom accessories using 3D modeling software to personalize this tiny abode. Print without supports, then snap off the thin support rods beneath the roof after printing is complete. To install the LED, attach one leg of the LED to the top half of the coin cell battery and bend the legs as shown in the images above. This will ensure the LED only lights up when pressed against the battery. Place the LED inside one of the designated holes within the home model and secure it with a small amount of superglue to hold it firmly in place.
