You'll need to put your own light or xmas lights inside. Print everything, I added square blocks that you can stick your xmas lights wire in to hold them in place (you'll have to glue them on the flat side), or just glue the lights directly to meeple side. Run the lights through the hole in the big meeple, Attach the lights to thin meeple side, put the cylinders in the indent on the thin meeples hands (glue). This is so you can open it up if you need to get in there.
I printed at 2.4 layer height, 205c with white PLA. 10% infill if you want but you can do 0%. Do not print with supports on the big meeple side. The cylindars on his hands will print a little sloppy but it should bridge and wont be an issue and you wont be able to see them anyway once assembled. If you do supports, you will put a blemish on the inside and the lights will show it.
