These are pretty simple. They are small pegs that hold neon-style led lights onto the honeycomb storage wall. There are two options because the storage wall is not square, so going vertically and horizontally isn't really possible with one piece.

I personally printed them with clear PETG with the default settings for my printer. Since they are hardly noticeable, I didn't spend much time attempting to make them perfectly clear.

one last note, I normally like to share my files for creation but I somehow have lost the file in fusion that I created for this. Worst case if anyone needs the file I can remake the parts, they weren't very complicated.
