Menger-Style Rhombic Dodecahedron Fractal | Level 3

I made this model while exploring fractal geometry using CAD software. Because of the complexity, slicing can take a while and you’ll want a decent PC to handle it smoothly. The print itself is also a long one. The example print shown took close to 43 hours, but the result is absolutely worth it and looks especially stunning in dual or tri-color silk PLA.

Please note: The STL and 3MF are provided at the same scale shown in the photos. If I were to reprint it, I might scale it up by at least 15% to bring out more detail in the smallest rhombic holes. Using a smaller nozzle is another option, though it will add quite a bit of print time. The print came out great as it is, but I would have preferred a little more definition on the smallest rhombi.



Print Settings (I Used the Bambu Lab P1P):

Please double check adhesion settings before starting this print!

This model has a relatively small base and a much larger top section, which makes it top-heavy. A brim is required for stability.

The included 3MF was sliced and tested on a Bambu Lab P1P with a brim enabled by default. If you change printer, plate, or filament profiles, your slicer may override certain settings (including the brim). 

Nozzle: 0.4 mm
Layer Height: 0.16 mm Layers with 0.2mm Base Layer
Infill: In the included 3MF, I set the infill to 10% Gyroid, but the geometry causes the part to print mostly solid anyway.
Brim: Use both an inner and outer brim for stability and proper adhesion.
Supports: None
Bottom Layer Pattern: Hilbert curve (Optional - I think it looks cool but it's not necessary.)

Don't forget to check out Level 2! The model is also available on my page now: https://www.printables.com/model/1388512-menger-style-rhombic-dodecahedron-fractal-level-2
