I wanted to keep swatches from different filament batches with room to expand, and none of the existing models had the size or flexibility I needed. I designed this from scratch in openscad using the official swatches as reference, and it could be easily resized. At 25mm spacing (and 24mm swatches) there wasn't much space left between them, so I reduced the keying to just the corners. This also allows the possibility of designing a 3d-printed label that crosses multiple positions.
