I thought of this chain for the X motor thread inspired by 2 existing rows, the final part is not fixed but if like me you have the original fixing of the wire will help you keep the chain in position. the supports are necessary for the part to be fixed to the motor.
EDIT 25/03/18: Thanks to iann finney for creating the end of the chain that fixes it to the structure and for revisiting the support that goes to the engine! nice teamwork, good print to all of you
EDIT 24/06/18 new version of motor mount , now can fixed chain
