Filament Swatch Generator

Filament Swatch Generator 

By default, this creates a business-card-sized swatch 3 mm thick, with a thickness gauge from 0.2 to 2.8 mm.  Labels can be set to identify the filament in use.  Use something like this to generate a swatch: 

openscad filament_swatch.scad -o swatch.stl \ 
 -D 'filament_brand="Veeology"' \ 
 -D 'filament_color="copper"' \ 
 -D 'filament_type="silk PLA"' \ 
 -D 'hotend_temp="210"' \ 
 -D 'bed_temp="60"' 

For printing, it is recommended that the first-layer thickness is set equal to the default extrusion width.  Also, it may be necessary to print the text with a thinner extrusion width for it to be fully rendered; in PrusaSlicer, you can use a height modifier from 2.6 mm (default) on up to set the external perimeter extrusion width to 0.25 mm.
