Print the required parts. I used white PLA for all 3 components, but you could use different colors. If you don't plan to paint anything, I would suggest using a red PLA for the cap, white for the stalk and underside. The thin underside transmits light well, but you could experiment with a more translucent material.
I alternated between sanding and applying sand-able spray paint until the desired smoothness was achieved for both the stalk and the cap. The underside should not be processed because its pretty delicate at this stage. I then spray painted the cap with glossy red spray paint, and speckled it with white acrylic paint by flicking a paintbrush at it. The stalk was spray painted with glossy white, and both were then clear-coated.

Assemble the top
Install the LEDs of your choice. I used double-sided tape to attach them to the cap. Then epoxy the underside to the top of the cap. I used 2 part epoxy to glue everything together in this project.
Super cool project! Can you add a reference URL to what libraries or project code you used on the Arduino? If it's entirely custom and you don't want to publish or share it, include references to the articles or projects which guided you to your final implementation. Thanks!
