Fibonacci Spheres

OpenSCAD script that uses a projection of the Fibonacci Lattice to generate a spherical model with an arbitrary number of cutouts evenly distributed across the surface. The implemented code is less than 20 lines making the algorithm a very elegant solution to generating a customizable airless ball.

Printing Tips

The included example print profiles have settings I've found work well for spherical models without the use of dedicated support filament. The profile is based on the “0.20mm Standard” profile from Bambu Labs with manual supports enabled. You can paint supports to the outside of the model for all layers under a threshold using the method shown below.

Multi-material Supports 

For users with multi-material capabilities another option is to use a dedicated support filament to make them easier to remove (at the cost of purged filament). This is done by selecting the filament to be used for support base and/or interface layers as shown below.

The above example shows PETG (red) being used as a support interface for the print in PLA (blue). The result is a small layer of PETG applied between the PLA model and supports that is easily removed from the finished print.
