Sacrum with Connecting Ball Join to Spine: Remix

thingiverse

Remix of original 3D model from DaveMakesStaff by adding connecting ball joint at the bottom of the L5 and adding the receiving socket on top of the Sacrum, both L5 and Sacrum can be connected together. I printed most of the Cs, Ts and Ls with 90 degree rotation, so the ball joint and the receiving socket are both lined up horizontally minimize the support and adding the strength to the connections.
