Surely cxom had planned every single part to be connected to the part before and after. So even if we get a hold of all 75 parts it's still useless if we don't also have these coordinates (unless everything fits exactly in the right order).
Ganja, everything is quite detailed in
this document
You have each sections x-y-z coordinates and the type of section
each section can have entry and exit on different sides of the "cube" but vertically they are always either:
entry on top exit bottom or reverse
the types of sections are :
Curve Ups (entry on bottom, exit on top on adjacent "90 degrees wall")
Curve Downs (same as above but entry on top level exit on bottom)
Straight Ups (entry on bottom, exit on far parallel wall)
Straight Downs (...)
Invert Ups (i think inverts are like "u turns" where the entry and exit are on the same wall)
Invert Downs
so the info is there... its just hard to source the parts and to find someone motivated to do the joining / fixing =)
