Looks mixed up when I render it.

I checked with a scale 10 times larger for everything and then I see what
you are trying to make. So, must be the tiny sizes causing the trouble. I
guess 4 times larger fixes it, meaning an end result of 0.04 for the minimum
radius used in the sphere sweep. Much more than I'd have thought to be
needed. 0.02 unit radius used to be considered too small to work reliably,
for the sphere primitive itself, this is close to that. However,
improvements have been made and yet this doesn't seem to have helped the
sphere sweep. I don't remember much about it's progression though, so I'm
just conveying what I believe might be relevant.
