I redesigned this famous but rare space brick in two versions: one large, with slightly rounded edges, and the other small, already colored for multimaterial 3D printers. I used Prusament Gravity Grey, but with difficulty: I found that it clogs 0.2mm nozzles, so the color would be very close, but the filament material is full of impurities, and there are also known adhesion problems. Therefore, I recommend using another brand with a similar shade and using a 0.2mm nozzle with a layer height of 0.10mm if you print the 1:1 version.
