Filament Sample/Tester Cards

I needed some test cards for my filament selection, so I made these using openscad. Included a lot of pre-made stls and the parametric openscad file.

Box for cards here: https://www.printables.com/model/438655-box-for-filament-sample-cards 

The cutout top marker is to separate brands and types in the box (also to have some structure from the side).

Recommend slicing with 0.2mm layers (the thickness tests are n*0.2mm).

Also I'd suggest printing at least 2, maybe 4 cards of each filament. :D
