# LED Trinket Tree Topper ## 3D Printing # What your Christmas tree needs this year is a Trinket-LED animated Moravian Star! Moravian Stars come in various sizes and number of facets... the most common is the 26-point form which is composed of eighteen square and eight triangular shaped points. The star featured here is an adaption, using one of the points / facets to mount the star atop a tree. ![](https://cdn-learn.adafruit.com/assets/assets/000/012/620/medium800/trinket_IMG_0449.jpg?1386049186) The shape is technically known as an Augmented Rhombicuboctahedron. Say that ten times fast... If you favor durability, print-up your parts as-is with your favorite transparent or semi-transparent filament. If you want something lighter, you can go with one layer + zero in-fill.
