SLC Temple Ornament
thingiverse
I scaled it down to about 50%, added a loop to use as a hanger, and printed it with 0% Infill and 1.7mm shell thickness (4 shells) and 0.01mm bottom thickness (1 layer). I cut the bottom out and glued it to a 2xAA battery holder (http://www.digikey.com/short/tz5bd1) which had a switch (https://www.digikey.com/short/qcwd5b) and 10mm white LED (https://amzn.com/B00KNTP936) hot glued to it. It pulls about 7 mA, so should last the entire holiday season (I hope). If I was going to do it again, I think I'd go with AAAs since it is a bit heavy for an ornament, and I don't think the battery life is an issue.
