Printing Information:

• Use tree support to support the voronoi structure. 35° overhang threshold with 4mm base brim works.
• Use a brim to improve the contact surface with the printbed
• 5% infill is fine, infill shouldn't affect the voronoi but the stone will use less filament.
• If you want you can split the model to its parts and print the rock in another color with an MMU
