Drive Chain fully parametric

build your own drive chain with the parametric chain.scad script
or just use one of the exampels (test_chain.scad)

__example 3__
- real strong chain but can not be decomposed

__example 4__
- same like example 3 but the first chain-link have a snap_fit hinge

__example 5__
- another easy assembly / disassembly chain hinge
- this chain is bigger then the other examples
