I know the monolith has NO markings of any kind, but it has been 47 years (I think) since the movie came out so I thought a small reminder of where it came from was in order. Anyway it is 1 cm by 4 cm by 9 cm. And you better make it black, and stay away from Europa.Use Black! I printed it on the side cause I thought laying flat would make it hard to remove and standing up might cause it to tip over. I sped up the perimeter to 50 mm/s and used 15% infill.
