This is an updated version of a previous design of mine which reflects the year change, as well as a few other minor tweaks. I have also included a set of beveled edge ornaments, to go with the original rounded edge version. You print a front and a back of the style that you desire (with or without the year). I found that printing with supports on 15 degree angles, or less, works pretty well – supports are mainly placed under the hat area. This makes clean-up easier. The halves can be secured together with a ribbon through the eyelet in the hat. A tree hanger ribbon would also use this eyelet.
I designed this a few years ago, initially to store a USB drive. I have since modified it and two years ago, I placed a little money inside as a prize for the first person to notice that there was something inside the ornament.
The author remixed this model.
