Fireprinto, you could split the inner core in two pieces and print seperatly, bridging should work since the inner is square.

The outer not a clue.

Just some observations from the picture of what you trying to create:

  1. The assembled version never had any windings installed, part of the tape is scratched of showing an empty groove.
  2. The D connector at the top has never been connected to, you can still see the raw pin
    s, no cable ends attached or solder residue.
  3. The inner core your making has a square center, the original is not.
