Filament swatch

Existing swatches didn't meet my needs so I designed my own. This will take a 15mm high by up to 50mm printed label in the recess. A transparency-level panel is integrated to show how opaque the filament is at 0.4mm, 0.6mm, 0.8mm and 1.0mm thickness i.e. 2-5 layer thickness when using a 0.2mm layer height process.
