Multilevel shaft
In Orbitech we introduce a new feature with gear shapes, Multilevel Shafts.
Every gear shape has 3 variants, Bottom, Center and Top and you can cycle between them using the Wrench or the Iron Hammer Tool.
Variants can be also obtained in the Builder's Bench

Each level does not connect with the others, unless a certain shape matches in a certain position, allowing you to create more complex shapes and mechanisms and compact them to take the less space possible.
Cages are designed to connect with every shaft level, allowing you to connect, for example, bottom with top gears
