Influenced by Duke Dokshttps://www.youtube.com/watch?v=3Mkf67_ZnEMInspired by him, I made these Christmas letters according to his tutorial.

It takes about 10 hours to print the outer layer of each letter, while the inner layer only takes 2 to 3 hours.

The size fits perfectly, and there are holes reserved inside for installing LED strips. I just need to wait for my own equipment to arrive before I can start installing it.
