Tiles for quickly seeing all available filaments and colours. No need to print a #3DBenchy every time a new filament arrives, only takes roughly 4g of filament to print.
Notes
Remade hole cut to be more round and symmetric
Remade corners to be more round
Resized the card a bit to shrink in height, from 40mm to ~35mm.
Added a “window” with different heights to show the appearance of the filament with different layer numbers. Printed at 0.2mm layer height from left to right goes from 1 to 5 layers.
F3D file is available for further customization and tile creation.
