Spherical Halbach magnet array - 3 different sizes

This is a spherical (halbach) magnet array that fits 5mm cube magnets.
You can arrange the magnets in a halbach array pattern to get the strongest field.
You can also arrange the magnets equally so all poles of the magnets face the same directions or in an alternating north-south pattern.

Be creative and find an arrangment pattern that fits your needs the most.
The holes for the magnets are 5,1mm large, if you want a thighter fit, just scale the print down a bit.
