Nontrivial Pyraminx by Timur

Nontrivial Pyraminx is an attempt to make a more difficult puzzle out of Pyraminx.
Its tips are not trivially independent, but internally connected so that they can only turn together.
Two of the tips are "fast" and the other two are "slow".
Any tip can be turned, but the fast tips would turn 2 times faster that the slow ones.
The rule is to always turn a tip together with the middle layer (else it would be as easy as Pyraminx).

The mechanism contains 10 gears, among which are 6-, 9-, and 12-teeth gears in a tricky combination
