More mechanical parts.

More mechanical parts that could also move with  flexibility on how they connect would open up a world of in game engineering comparable to minecraft e.g pistons and rotating bars or ropes.

I would like to see t-cross sections with the axels and rotors. Based on how they designed them, it looks like it should be able to work. It would be nice to split power in a way that doesn't require such a large part.
