Light Up House Keyring

thingiverse

This tiny house print can be assembled with a coin cell battery and cathode LED. When the button is pushed, the light in the house comes on and you can see a small table and chairs. Add in your own accessories into the house to personalise with your favourite 3D modelling software. Print without supports, snap off the thin supports under the eaves after printing. To install the LED, tape one leg of the LED on the top half of the coin cell battery and bend legs as shown in images above so that the LED will only switch on when pressed against the battery. Install inside one of the LED holes in the house and use a tiny bit of superglue to secure the base in place.
