I suggest that the 3 orthogonal dimensions enforce that jet shape
and the evidence is new! The cube at the center of iron is
the realistic shape of a static nucleus. The Simple Cubic
core of the elements is evidence of the strict 3D basis
that made those 3 jets of hadrons.
I don't have any reason to think
that the atomic nucleus isn't
billiard ball or plum pudding.

Not even wrong.

There are scattering experiments by Rutherford et al. that *show* it is neither.

Not really, in ANY sense.
3-jet events were not observed until well after QCD and the standard
model were formulated. Basically it takes high energy to be able to
identify jets as jets [#], and this pretty much had to wait for LEP and
the Tevatron -- at lower energies the particles of different "jets"
overlap too much. The kicker is that 3-jet events were seen first in
e+e- collisions, in which there are no quarks in the initial state --
since quarks can only be created in pairs, having THREE jets is evidence
for GLUONS, not quarks.
[#] in the sense of being an initial quark exiting a
pointlike high-energy interaction that became "dressed"
into a bunch of nearly co-moving hadrons.
The original motivation for quarks was the observed patterns in meson
and baryon masses, spins, parities, and decays. This was long before QCD
and the standard model, but became the basis for them.

Right -- that is not even wrong. Here there are THREE coincidences that involve the number 3:
a. we see 3 spatial dimensions
b. baryons have 3 valence quarks [@]
c. there are 3-jet events
As far as we know today, there are indeed COINCIDENCES:
For (a) -- what about the 4th dimension of time?
For (b) -- what about mesons with 2 quarks?
For (c) -- what about 2-jet and 4-jet events?
[@] Baryons have LOTS more inside than just 3 quarks.
For instance, the proton has a mass of ~ 938 MeV, but
the rest masses of its three valence quarks sum up to
about 9 MeV (!) -- there is A LOT more going on in there!

billiard ball or plum pudding.

Plus all the evidence supporting the standard model, which is
essentially every one of the many thousands of particle experiment ever performed.
