2035-03-20 - Update - v1.2:
I've increased the thickness of the Collar to be a multiple of the 0.4mm standard nozzle size.
I've added 0.05mm to the inner diameter of the Collar to avoid both the Collar and the Ornament occupying the same space. The result is a much better fitment without the need for sanding or other adjustments beyond any dealing with any stringing or seam issues you may encounter.
I've redesigned the lettering on the Collar to greatly improve printability and significantly reduce the post-processing required. For me, all it takes now is a quick pass with a torch for the strings and a trim of the bottom from where I used a brim.

Gold: v1.0
Silver: v1.2
Note that I've removed the previous version of the Year Collar, but have now included both a 2024 and 2025 version.
If you need to modify this in any way, here's a link to my OnShape document:

Original - v1.0:
This is a Year Collar for the referenced ornament.
The Collar can be left unattached, but I suggest gluing it down. A spritz of distilled water on the ornament will help activate CA glue on the collar. Place, adjust, and then press and hold for at least a minute to ensure adhesion.
I will note that, depending on your printer and filament, you may need to do some delicate post-processing to clean up the characters. (I spend a good 10 minutes on each one. YMMV)
The cap shown is my own Parametric Ornament Cap and I have included the size which fits this ornament. I will post a link to that full design at a later time.
Cheers!

Always Be Printing
The author remixed this model.
This is an add-on to the original model, not actually a remix of it.
The Year Collar is used to identify for which year's Christmas the ball was printed.
