About this 3D model

This is a fast medium of use I developed specifically for wire strands Filo3D (sold Dagoma) in order to proceed in this thread without any problems. By applying a rotation in the central cylinder mechanism, the 6 arms diverge and come keep the coil of wire. Assembling all locked except 4.2x16 6 screws (or 4.2x13) like "sheet metal screws" Phillips to fix the forks.
