Has anyone seen a better SMOT toy than this one?

So, other than the in the form of the 3D printing file, are there specifications
available some where, of the shapes and dimensions of the two plastic parts,
the ball used and the magnet used  in the video @

Long ago, a member named Clanzer proved that the rotational momentum of the ball
is exactly the same value as the same mass on a cart with wheels
Therefore: the rotational momentum does not add anything that would not otherwise be there

We may find the exact same results on a flat track

You may need to word that a bit more specifically for it to be either correct of false.

When a mass falls along a path that forces rotation that rotation MUST come at the cost if advancement along the path. Same energy contained, just left advancement speed. A spindle on tracks just won't speed up like a ball, let alone a ball with a heavy center surrounded by low density material.

If this doesn't work, I'm sure a flat track will be no better, or even worse.
If it does work, I doubt it will also work flat. Making it work in a more industrial manner would be great fun.

Best might be if someone could convince the inventor to send over a working model. But if someone wants to commit for a replication: EPIC!

In my humble opinion...

The variations of this device from other such magnet ramp designs,
would not result in a self runner.

But still it remains, that I would like to see a practically identical replication done
by someone I trust.
