NASA's iconic worm logo on an angled plaque. Approx 170 mm (6.75") long.
There are two sizes in the 3mf. 170 mm and 100 mm. I haven't printed the 100 yet, but that's coming. I printed the 170 using Prusament Mystic Brown and I left .20 layers going up the face of the plaque so that the prismatic filament shows up better.
