ETD 49 EC 49 bobbin

Didn't feel like paying $2.5 dollars to epcos for ordering these by the hundred. So I made my own for printing. For the split model, you must have support roof enabled in Cura or you won't be able to fit the Ferrite core into the bobbin. Utilize super glue to weld the two parts together. The two pieces are keyed to fit in one direction only.
The non split version will need a lot of support, almost as much as the bobbin itself.

All versions connect to the PCB via 4 4-40 screws. Drive them in
