New Drive Shaft

This design have 4 points of attachment so it will never give problems like the 2-arms ones.

To enlarge it, move the sublayer beams arms and deatach their central section and make it longer at any size, then attach your new piece using the 2 older parts remained (which are connected to the cylinders).


-Edit
Health not the best since beginning of december so that taking me more in the bed than at pc :(
