I took a 3d scan from the scantheworld group and split it into 3 pieces so that it may fit on my printer. I then put pins in each piece so it fit nicely together and used some glue to keep it together.
Here is the original source I got the Scan from https://www.myminifactory.com/object/3d-print-human-femur-43321
