That might be the cause of the slowdown. I mean, superellipsoids are slow,
but not *unbearably* slow in my experience.

Try this: rather than doing this:

difference {
union {
// superellipsoids
// other stuff
}
union {
// big hole cutout
}
}

do this:

#declare bighole = union {
// big hole cutout
}
union {
difference {
union {
// other stuff
}
object {bighole}
}
difference {
union {
// superellipsoid 1
}
object {bighole}
}
difference {
union {
// superellipsoid 2
}
object {bighole}
}
...
}

I wouldn't be surprised if that speeds things up.
