Paint your own Christmas tree decoration! You can paint directly inside the “frame”, or you can glue a piece of paper, a photograph, etc.
I printed a few of these to keep the kids entertained for a while. I printed them in slightly-translucent UV-reactive PLA, so you can see the infill pattern through them. I did each one with a different infill pattern to make them unique.
