Summary

Improvement and an extra variation of Axel Fischer's "FT Fischertechnik Kabelführung".

The original 'Statica'-clip was just slightly too thick to fit through the hole. Furthermore the shaft was a bit too long, so the clip was mounted quite loose. So I redesigned this 'Statica'-type clip, and added a variation with a 'feather'-nut to be used on normal fischertechnik building blocks. This one can also be used on the ones with shallow grooves.
