Ball caged in tetrahedron

Just a fun doodad. The cage has triangular shaped beams making up a tetrahedron. The ball is built inside.

Separate ball & tet files allow you to make it in two colors if your printer supports it. However, it may be possible to make the ball first, then make the tet, pausing the job as it gets taller than the ball and insert it before finishing the tetrahedron job.
