Connecting multicube assemblies to a base plate
Self-supporting Multicube System: An Example
Even this rather complicated and large assembly of multicube elements is only connected to the base plate at one point. It is sufficient and does not affect the stability or durability of the Fiber Port Cluster in any way. More information and other Fiber Port Clusters can be found here or in an article here.
Negative effects of multiple connection to the base plate
If one would rigidly connect the multicube-based system at several distinct points with a base plate there would be the risk of mechanically stressing the system: the coefficient of thermal expansion of aluminum (base plate) is different to stainless steel (the rods).
