I'm not paying $2.5 for EPCOS to order these by the hundred, so I made my own for printing. For the split model, support roof must be enabled in Cura or you won't fit the Ferrite core into the bobbin. Super glue is used 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 that can be driven into self-tapping.
