I created my ornament using Tinkercad. I don't have access to a 3D printer, so I don't have any idea how this looks in real life. If you do decide to print this out, I'd love to see how it looks!
When I think of the holidays, I think of gifts, stockings, and candy canes. And I like to associate winter with penguins. So, I put all of that together to have a penguin popping out of a gift box holding a candy cane and stocking! And since this is for the 3D Printed Ornament Design Challenge, I made it a little Americana by giving the penguin a colonial America-style wig.
I have provided an STL file of the ornament. I hope you like it!
