Here's my 2021 Christmas Ornament for your consideration. I created various versions that I will describe below. My original was printed with 5 colors (I chose white/black/green/silver/red) to highlight the various portions of the design. Each color layer is 1 mm (unless you use the shorter version).

You may not care of my sense of humor with the text "the gift that keeps on giving." So, I made versions without that text.

I made versions with and without the ring to use for ornament hooks. You may be able to tie string/thread to the mask ear straps if you prefer.

I admit it's a little large, but I struggled to get good line closure with anything smaller. I use Prusa Slicer and increased my "infill/perimeters overlap" to 50% and reduced the "slice gap closing radius" to .0049 (from normal .049) to get my best results. I recommend .2 mm layers as they match well with the layer heights in the design.

Variations:

• no hook = no loop at the top for a hook
• thinner = color layers are .6 mm instead of 1 mm high
• no text = without the "the gift that keeps on giving" text
• same height = the 2021 and text are all at the same height if you prefer single color or will just paint it

I took photos of the original, the "thinner" version (with an off-white background to mimic a "well-used mask"), and the "no text" version and tried to show the differences. I did not print the "same height" or "no hook" versions, but I am confident they should work as well as the others.

Credit where credit is due:
I took the 2021 from Bahnamoon's 2021 COvID Ornament (https://www.thingiverse.com/thing:5153566) and the surgical mask from https://lovesvg.com/product/free-surgical-mask-svg-cut-file-2/

2021-12-17 update - removed all files and replaced. I realized the back logo was way too deep. It is now more reasonable and shouldn't show through the print.
