While restoring my HS, I wanted to replace the plastic spacers. The short ones, which I had assumed were originally white, had gone yellow with age. At first, I 3d printed basic replacement cylinders, but after staring at those tree top images on the plastics I came up with the idea of turning the spacers into tree trunks. After trying out a couple different colors, I ended up liking the wood filament the most. They look great in the raw wood color, but they can also be sanded and stained for an even more of an authentic look.
