Well that is what my friend did, so he asked me to turn him into a star for his Christmas tree.
Of course you don't have to go with the silly choice of Keanu Reeves you can also design your own lithophane and add to the blank insert
The model is Based of the Star Topper with lights by Brian Zak
For my Remix i decided to use a Regular 5V led strip inside of the star, to illuminate the lithophane face.
The parts needed to recreate this:
TIP: For the most optimal prints print it all lying flat on the build plate and use only supports touching build plate for the star halves
The author remixed this model.
