Big Hollow Sphere HD

thingiverse

I tested my printer's capabilities by creating a large hollow sphere with thin walls, resulting in an impressive lightweight ball that slightly flexes. The model features 80K faces for optimal roundness. I printed mine on an Ultimaker using white PLA at a layer height of 0.09mm, printing speed of 50mm/s, without support, and a wall thickness of 0.4mm at 215 degrees, which took 12 hours and 24 minutes to complete. To achieve the maximum size your printer supports, scale the model and print it!
