Recursive Cube Cross Fractal | Level 3

This model is Level 3 of a recursive cube pattern, created in CAD by copying and arranging cubes into a layered geometric structure. A cut along a plane exposes a Level 3 Sierpiński triangle pattern inside the form. It works well as a display piece for desks, shelves, or as wall art. Printing only one half creates a flat back with natural openings that make it easy to hang on a nail.




Supports can be avoided by printing two halves and gluing them together at the base. Just make sure the orientation is correct before gluing, since lining them up takes a little care. 



Print Settings (Bambu Lab P1P):

Nozzle: 0.4 mm
Layer Height: 0.16 mm with 0.2 mm base layer
Infill: 10%, Gyroid
Top/Bottom Layer Pattern: I like to use the Hilbert curve pattern on the triangular faces. It’s optional, but it gives a nice effect.
Supports: None when printing two halves | Automatic Organic Tree when printing full shape.
Brim: Recommended for adhesion. I used a 5 mm outer brim on the larger half and the full shape, but no brim on the small halves.
