Here is my 2021 Christmas Ornament. I design one each year that I can customize with each family members name (look at my previous posts for examples).
This year I designed a multi-layer / multi-color design which uses M600 filament swaps every 0.8mm. I did this design in Solidworks and emboss cut each persons name in the back of the ornament. You can do the same using your software of choice (Fusions360, TinkerCad, or Microsoft 3D Builder, Etc).
I designed this in solidworks 2018, and have uploaded the native solidworks file. I have also uploaded STL's without names, and with/without the year. In addition, I have also uploaded Step, IGES, and X_T file formats for use in other CAD packages. Feel free to modify, reshare, customize to your hearts content.
I printed my versions in multiple colors of PLA. First white, then light brown, then dark brown, then black, then finally a silk red.
