Hello everyone! Today, I came up with an idea to create a model using multiple materials in one model. More specifically, it's transparent PETG and PLA, so that you can illuminate it from the back and project some shapes. The inspiration came from this YouTube video, which combined them to create a display:

So in the end, I created a Christmas tree decoration, decorating a green PLA tree with red transparent PETG balls:

The three parts of the tree are identical and can self-assemble without the need for any glue. I also wanted the electronic components to be as simple as possible, so there's a hole in the base that can be used to place the positive electrode of the LED, and the other leg is placed on the negative electrode of the battery



Thank you, Bambulab! This multi-material design can be easily achieved! I hope you like it!
