Thank you @joochung for the cool idea and the cool files.
As I have to make some modifications and did not like to do them in OPenSCAD.
So I have put a part of the design into Fusion 360.
Stand up version for only one block, back to back.
You can select the amount of conductors by the parameter "Klemmen"
I have printed a version with 5 and with 3 conductors, works perfect.
