Decorative PCB Christmas tree

Updates

• 12/2025: Created additional PCB-themed ornaments for your (real) tree :)

• 12/2024: Added a version with a star as tree topper. The star is also available as a separate download and could be added to the tree afterwards, but the tolerances are not optimized for this.
