Margins are missing.

The head of tooth should not touch the foot of the opposite gear.

The part of teeth which get in contact should follow Euler's work, the
remaining part is irrelevant as long as it does not block the movement.

For less noise, consider a slanted rolling profil along depth (missing
the english word for that), and possibly a mirrored construction like
Citroën.

contact between any two gears should be limited to one pair of teeths,
one tooth per gear. (make teeth smaller).

Spur gear NEED a holding axis artefact.
