Suitable mechanisms

Basically just a list of mechanisms that could be useful for future advanced diamondoid gemstone based nanosystems.

Unlike in macroscale machinery with machine parts at the lowermost possible size limit there is no space for tiny screws and such to clamp together housings like gearboxes and such. This calls for different designs. See design principles listed on the page: RepRec pick-and-place robots (GemGum).

This also allows for interesting 3D printable mechanics that can cope without any metal screws.
