I printed the spinning “Swatch Display Tray” because I thought it was one of the best projects, simple and cool… but I didn't want to give up the different layer heights of the other related project the “Filament Swatch Card” (this one is cool but it leaves too much space between the cards from my pov) . So I adapted the logo with different layer heights to the simple square model and now I think it's the definitive swatch if you search a simple form, with some technical info that you could store in less space ;)

I tried to write on them but it's really a challenge… is too little for the 0.4 nozzle :(
