EtherCon Cable Drum - Inside Tail End Holder

I have the Klotz 50m stage EtherCon cable drum but it has no built-in solution for holding the inner short tail connector end. I resorted first to a short piece of elastic bungee cord that I would tie to the drum’s crank handle but that didn’t always work well as the connector didn’t always land at the same distance from the handle.
So I came up with this idea for a catch for the connector. It fits into the 55mm center hole of the drum and the EtherCon connector of the inner tail simply snaps on to it. The holding lips have a small edge that engages into the slot between the EtherCon’s body and the strain relief, this keeps the connector from sliding axially. The holder can rotate inside the drum’s hole so it can be aligned to any orientation of the final position of the connector.
The EtherCon connector can be inserted into the holder ether with the connector’s body between the lips, or if using an end cup (as in the pictures) the strain relief portion of the connector can be inserted, and the holder grips the connector just as well.
