I separated the block version of the tail into multiple objects to allow reorienting them individually. I had the best luck printing these with the female side resting on it's side flat on the bed. And then putting a support on the other(male) side.
Without this modification, the print would get >50% complete and when it was printing the topside of the female ends, they would collapse and I'd end up with spaghetti. The pre-assembled tail never worked out for me; each time I printed it, it would fuse completely.
