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 simplicity of the algorithm makes this a highly configurable and elegant solution to generating a customizable airless ball.

Printing Tips

The included print profiles have settings I've found work best for spherical models and is based on the “0.20mm Standard” profile from Bambu Labs with manual supports enabled.

Manual Support Painting

You can paint manual supports on 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 additional filament changes. 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 are easily removed from the finished print.
