A Rogowski coil is used to measure the current in a wire through the center of the coil. See for details for example:https://en.wikipedia.org/wiki/Rogowski_coil
The FreeCad script generates the body of a Rogowski coil with specified dimensions and windings etc. The gap in of the coil makes it possible to easily slide the coil over a current carrying wire (shown in gray on the first figure in the gallery)..
The windings on the coil are guided by small channels and there are two holes in the body of the coil to feed the incoming and outgoing leads. The wire at the end of the coil can be guided back to the beginning using the channel in the middle of the ring.
An alternative design for a Rogowski coil can be found at:http://www.thingiverse.com/thing:283430
