For 3.75, 6, and 12 inch figures.
Some folks were having trouble with the side arched sections (Drum 2 file) being too thin, so I've added a thicker version in the smaller scales.
It has come to my attention that there is a possibility that the drum is actually symmetrical (the string? part is supposed to be on both sides).
This is not visible in the movie or the Holiday Special. The part appears on the right in the movie (left side obscured), HS version, only on the left. At any rate, I've amended the folders to include a symmetrical version for all scales (see the last image), so you can make it as you see fit.
